Available in PDF, EPUB and Kindle. Book excerpt: This thesis describes my research into the highly tuned naturally occurring 3D photonic structures that are present on a selection of insects. The experimental and theoretical work presented in this thesis was performed in both the optical and microwave regimes. The work performed in the optical regime included both the geometric and optical characterisation of the native photonic structures present on the beetle Eupholus magni cus and the butter y Parides sesostris. The native photonic structures of these organisms were probed in order to determine their photonic responses and also to ascertain their geometries and structural classes. In cases where the geometry of a photonic crystal system has been determined, I have performed additional theoretical analysis of the structure to establish how it might be optimised for a particular optical function. The overall aim of the work performed in the optical regime is to further the understanding of the photonic structural designs present on a selection of beetles and butter ies, by both identifying and characterising their underlying structural geometries and consequent photonic responses. Eupholus magni cus is a species of weevil that produces its coloured appearance from photonic structures that are present on its outer wing casing, producing a striped coloured pattern. The photonic structures that I discovered were present on this weevil were found to be contrasting in structural order. I used a wide-ranging variety of experimental and theoretical techniques in order to perform an extensive electromagnetic and structural characterisation of these contrasting structures. The two contrasting photonic mechanisms employed by E. magni cus were found to produce a similar optical response in terms of angle-independent colour whilst re ecting di erent coloured hues. Parides sesostris is a species of butter y that uses a gyroid photonic crystal structure, contained within scales, to produce green coloured patches on the dorsal side of its wings. In addition to this, P. sesostris uses embellishments to its scale morphology in order to produce a highly tuned angle-independent optical response. The optical e ects brought about by these structural embellishments were investigated with optical experimental techniques and they were found to di usely scatter light and aid iridescence suppression. In addition to this, theoretical modelling was performed on a variety of gyroid geometries. The gyroid photonic structure found in the wing scales of P. sesostris was determined to be highly optimised to re ect the largest range of frequencies possible from this geometry, also aiding iridescence suppression. In addition to this, the arrangement of gyroid arrays within each scale was determined to produce the highest intensity possible by using the smallest possible number of unit cells. In addition to the optical characterisations of the organic naturally occurring photonic structures found on these organisms, I also synthetically replicated the three fundamental naturally occurring triply periodic bicontinuous cubic photonic crystal structures for experimental and theoretical electromagnetic characterisation in the microwave regime. The microwave regime was selected to perform the characterisation as a high-resolution fabrication method can be employed in order to produce millimetre-scale structures, suitable for probing in this wavelength regime. A high resolution fabrication method is an absolute requirement for accurately replicating the complex geometries of constant mean curvature structures and retaining a high level of detail. I have electromagnetically characterised these three structures with the aim of gaining a better understanding of their polarisation-dependent photonic stop-band responses. Speci cally, I have identi ed the origin of, and the dispersion of, photonic stop-bands produced by each unique structural geometry. I have principally focused on the characterisation of the electromagnetic responses of these structures, how they di er from each other and also why a linear polarisation dependence arises from these 3D photonic structures. In addition to this I have related the electromagnetic responses of these structures to analogous optical structures that naturally occur on the wings of the butter y P. sesostris and elytra of the weevil E. magni cus. With this I aimed to gain a better understanding of the origin of the optical e ects they provide the host biological system. This includes the characterisation of the gyroid photonic crystal structures, chosen to mimic that found in P. sesostris wing scales. The results from this were also subsequently used in the optical optimisation examination performed on the P. sesostris gyroid. Finally, I have investigated a dynamic aspect of the 3D gyroid photonic crystal, formed from a constant mean curvature surface. A compliant gyroid structure was fabricated for analysis in the microwave regime and a systematic compression force applied to it. I have measured the electromagnetic response of this compliant gyroid at each compression distance. Alongside this, I used theoretical modelling to electromagnetically characterise an analogous system under compression. In doing this I have identi ed the origin of the novel and complex photonic band-shifting behaviour produced by this 3D geometry.

Available in PDF, EPUB and Kindle. Book excerpt: Just like the periodical crystalline potential in solid-state crystals determines their properties for the conduction of electrons, the periodical structuring of photonic crystals leads to envisioning the possibility of achieving a control of the photon flux in dielectric and metallic materials. The use of photonic crystals as a cage for storing, filtering or guiding light at the wavelength scale thus paves the way to the realisation of optical and optoelectronic devices with ultimate properties and dimensions. This should contribute toward meeting the demands for a greater miniaturisation that the processing of an ever increasing number of data requires. Photonic Crystals intends to provide students and researchers from different fields with the theoretical background needed for modelling photonic crystals and their optical properties, while at the same time presenting the large variety of devices, from optics to microwaves, where photonic crystals have found applications. As such, it aims at building bridges between optics, electromagnetism and solid-state physics. This book was written by six specialists of nanophotonics, and was coordinated by Jean-Michel Lourtioz, head of the Institut d'A0/00lectronique Fondamentale in Orsay and coordinator of the French Research Network in Nanophotonics.

Download or read book Photonic Crystals written by John D. Joannopoulos and published by Princeton University Press. This book was released on 2011-10-30 with total page 305 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since it was first published in 1995, Photonic Crystals has remained the definitive text for both undergraduates and researchers on photonic band-gap materials and their use in controlling the propagation of light. This newly expanded and revised edition covers the latest developments in the field, providing the most up-to-date, concise, and comprehensive book available on these novel materials and their applications. Starting from Maxwell's equations and Fourier analysis, the authors develop the theoretical tools of photonics using principles of linear algebra and symmetry, emphasizing analogies with traditional solid-state physics and quantum theory. They then investigate the unique phenomena that take place within photonic crystals at defect sites and surfaces, from one to three dimensions. This new edition includes entirely new chapters describing important hybrid structures that use band gaps or periodicity only in some directions: periodic waveguides, photonic-crystal slabs, and photonic-crystal fibers. The authors demonstrate how the capabilities of photonic crystals to localize light can be put to work in devices such as filters and splitters. A new appendix provides an overview of computational methods for electromagnetism. Existing chapters have been considerably updated and expanded to include many new three-dimensional photonic crystals, an extensive tutorial on device design using temporal coupled-mode theory, discussions of diffraction and refraction at crystal interfaces, and more. Richly illustrated and accessibly written, Photonic Crystals is an indispensable resource for students and researchers. Extensively revised and expanded Features improved graphics throughout Includes new chapters on photonic-crystal fibers and combined index-and band-gap-guiding Provides an introduction to coupled-mode theory as a powerful tool for device design Covers many new topics, including omnidirectional reflection, anomalous refraction and diffraction, computational photonics, and much more.
Book Synopsis Topological Photonic Crystals in One, Two and Three Dimensions by : Sachin Vaidya
Download or read book Topological Photonic Crystals in One, Two and Three Dimensions written by Sachin Vaidya and published by . This book was released on 2023 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The recent discovery of topological phases of matter has revolutionized our understanding of condensed matter systems. The information that describes these phases is stored across the entire system, and as a result, some of their properties are protected from local perturbations. These systems exhibit unique phenomena such as transport channels that exist on their boundaries and features that are robust to disorder. Topological phases were first discovered in condensed matter physics but the underlying principles were soon extended to many wave systems such as photonic and acoustic systems. The field of topological photonics aims to both realize novel topological phases in photonic systems and develop applications based on their robust properties. This dissertation aims to further our understanding of topological photonics and lies at the intersection between photonic crystals and topological band theory. In the first two parts of this dissertation, we present two studies that experimentally realize charge-2 Weyl points and observe their splitting in three-dimensional chiral woodpile photonic crystals. This is done at technologically-useful infrared wavelengths by using a state-of-the-art 3D micro-printing technique that employs low loss materials. In the next two parts, we focus on developing a complete topological classification of bands in one- and two-dimensional photonic crystals under crystalline symmetries. Based on this classification, we propose a strategy to diagnose and design a wide variety of topological photonic crystals. We then use this framework to show that Chern insulators can have a meaningful notion of relative polarization whose effects can be seen at the boundary between two Chern insulators with the same Chern number. In the last two parts, we explore miscellaneous topics in photonic crystals. In the first of the two parts, we theoretically predict bound states in the continuum that are localized to point defects in two-dimensional photonic crystals. This allows for the confinement of light in the absence of photonic bandgaps. In the last part, we present the observation of a localization transition in one-dimensional photonic quasicrystals. In addition, we observe a surprising phenomenon that occurs in this system, a second transition of some states to a delocalized regime upon further increasing the quasiperiodic disorder.

Download or read book Fabrication and Characterization of Three Dimensional Photonic Crystals Generated by Multibeam Interference Lithography written by Ying-Chieh Chen and published by . This book was released on 2009 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Multibeam interference lithography is investigated as a manufacturing technique for three-dimensional photonic crystal templates. In this research, optimization of the optical setup and the photoresist initiation system leads to a significant improvement of the optical quality of the crystal, as characterized by normal incidence optical spectroscopy. Theoretical spectra are calculated and demonstrate close agreement with experimental values, indicating that this fabrication process achieves excellent optical quality. X-ray microscopy provides non-destructive inspection of the fabricated crystals at nano-scale resolution. A reconstructed crystal model is generated by computed tomography which allows for comparison to a predicted structure's geometry and optical spectra. Using the polymer crystal as a template, electrodeposition is performed to completely infiltrate the crystal with Cu2O. After polymer removal the inverted Cu2O crystal exhibits a high peak reflectance at the predicted wavelength, indicating the structure is an exact inverse of the template. A conformal growth algorithm is developed for the commonly used chemical vapor deposition infiltration technique to explain growth results and verified experimentally with atomic layer deposition of oxide materials. Finally, a customized chemically amplified positive photoresist system and its processing steps are developed as a route to zero-shrinkage template material for high fidelity patterning of the designed interference patterns.
