Book excerpt: Photonic band gap materials (or photonic crystals) are periodic dielectric structures with periodicities comparable to the wavelength of light. They offer promising solutions to various scientific and technological challenges. The work in this thesis is focused on fabrication and characterization techniques for photonic crystals and the study of linear and nonlinear optical phenomena in these periodic structures. brief theoretical background of photonic band gap materials is provided in chapter 1. Chapter 2 describes a method for the fabrication of highly ordered photonic crystals by using self-assembly of colloids of dielectric spheres. In this chapter, the conditions that increase the level of perfection and the factors that give better control over the crystallization process are investigated and their theoretical interpretations are discussed. Also infiltration of a high refractive index material (GaP) into the crystals is investigated. Methods for generation of third harmonics in two different photonic crystal media are presented in chapter 3. In the first case, observation of a highly enhanced one-step, third-harmonic generation in three dimensional photonic crystals formed by close-packed polystyrene spheres in a face centered cubic arrangement, is presented. A near infrared laser beam, with a wavelength range of 1300nm-1900nm, is used as the pump source. In the second case, a strong enhancement of one-step third-harmonic generation in a one dimensional photonic crystal is presented. In this case, a near infrared laser beam is tuned to the low frequency edge of the band gap of a photonic crystal prepared from polymer dispersed liquid crystals by holographic lithography. Chapter 4 presents the results of linear and nonlinear optical studies in photonic crystal alloys which are formed by various compositions of polystyrene and polymethlymethacrylate colloidal spheres of the same size. Linear transmittance and reflectance measurements as well as third-harmonic generation experiments were conducted in these photonic crystal alloys. The observed experimental result is fitted to a calculated plot by assuming an effective dielectric constant for the colloidal spheres. In chapter 5, another promising method of fabrication of photonic crystals, holographic lithography, is described. A procedure and optimum growth parameters for the fabrication of fcc-like photonic crystals are presented. Summary and future plans related to the work in this thesis are given in the conclusions and future work section.

Book Synopsis Investigating Naturally Occurring 3-dimensional Photonic Crystals by : Caroline Pouya
Download or read book Investigating Naturally Occurring 3-dimensional Photonic Crystals written by Caroline Pouya and published by . This book was released on 2012 with total page pages. 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.

Download or read book Photonic Band Gap Materials written by C.M. Soukoulis and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 725 pages. Available in PDF, EPUB and Kindle. Book excerpt: Photonic band gap crystals offer unique ways to tailor light and the propagation of electromagnetic waves. In analogy to electrons in a crystal, EM waves propagating in a structure with a periodically-modulated dielectric constant are organized into photonic bands separated by gaps in which propagating states are forbidden. Proposed applications of such photonic band gap crystals, operating at frequencies from microwave to optical, include zero- threshold lasers, low-loss resonators and cavities, and efficient microwave antennas. Spontaneous emission is suppressed for photons in the photonic band gap, offering novel approaches to manipulating the EM field and creating high-efficiency light-emitting structures. Photonic Band Gap Materials identifies three most promising areas of research. The first is materials fabrication, involving the creation of high quality, low loss, periodic dielectric structures. The smallest photonic crystals yet fabricated have been made by machining Si wafers along (110), and some have lattice constants as small as 500 microns. The second area is in applications. Possible applications presented are microwave mirrors, directional antennas, resonators (especially in the 2 GHz region), filters, waveguides, Y splitters, and resonant microcavities. The third area covers fundamentally new physical phenomena in condensed matter physics and quantum optics. An excellent review of recent development, covering theoretical, experimental and applied aspects. Interesting and stimulating reading for active researchers, as well as a useful reference for non-specialists.
