Book excerpt: Puisqu’ils offrent la possibilité d’intégrer monolithiquement un grand nombre de composants à un faible coût, les circuits intégrés photoniques (CIPs) sont devenus une plateforme de choix pour la réalisation de capteurs optiques sur puce. Cette thèse propose, puis démontre l’utilisation de CIPs sur silicium pour la réalisation de polarimètres et de spectro-polarimètres sur puce. Dans le premier chapitre, nous présentons un séparateur de polarisation utilisant un réseau de nano-antennes en forme d’arêtes de poisson sur silicium. Nous montrons également qu’une structure de la sorte est en mesure de séparer deux états de polarisation arbitraires qui sont orthogonaux entre-eux. De plus, nous avons amélioré le précédent modèle théorique existant pour y inclure ce phénomène. Dans le second chapitre, nous présentons et démontrons de façon expérimentale un polarimètreintégré sur silicium qui requiert 6 photodétecteurs (6-PDs). Ici, la structure optimale veut dire que, pour un niveau de bruit donné, cette structure permet d’obtenir l’état de polarisation avec la précision la plus élevée. Nous démontrons également de façon théorique que cette configuration proposée peut maintenir un état optimal sur une plage de longueur d’onde de100 nm. Dans le troisième chapitre, nous proposons une jonction en « Y » paramétrisée dont le ratio de séparation de puissance peut être choisi avant la fabrication, lors de la conception. Sur une plage de longueur d’onde de 100 nm, les pertes de puissance de la jonction sont inférieures à 0.36 dB, et ce, pour tout ratio arbitraire de séparation de puissance. De plus, sa taille de1.4 μm × 2.3 μm le rend très compact. Au chapitre 4, nous proposons un polarimètre optimal composé de quatre photodétecteurs (4-PDs) possédant ces propriétés à partir de la jonction en « Y » proposée au chapitre 3. Un polarimètre non-optimal est fabriqué de manière à montrer la différence entre celui-ci et le casoptimal. Les résultats expérimentaux montrent que l’erreur de reconstruction du composant optimal est inférieure de 44 % à celle du composant non-optimal. Dans le cinquième chapitre, nous proposons et faisons la démonstration d’un spectro- polarimètre réalisé intégralement sur puce. Afin de permettre une analyse spectro-polarimétrique complete, quatre micro-résonateurs à effet Vernier compacts sont intégrés monolithiquementavec un polarimètre large-bande. Le composant optique proposé offre une solution de spectropolarimétrie sur semi-conducteur tout en gardant une taille très compacte de 1 × 0.6 mm2et une faible consommation de puissance de 360 mW. La détection spectrale pour tous lescomposants de Stokes est démontrée sur une large plage de longueur d’onde de 50 nm, etce avec une résolution de 1 nm par la caractérisation d’un matériau possédant une chiralitéstructurelle.

Book excerpt: This book provides comprehensive information on the history and status quo of a new research field, which we refer to as Engineering Optics 2.0. The content covers both the theoretical basis and the engineering aspects in connection with various applications. The field of Engineering Optics employs optical theories to practical applications in a broad range of areas. However, the foundation of traditional Engineering Optics was formed several hundred years ago, and the field has developed only very gradually. With technological innovations in both the fabrication and characterization of microstructures, the past few decades have witnessed many groundbreaking changes to the bases of optics, including the generalizing of refraction, reflection, diffraction, radiation and absorption theories. These new theories enable us to break through the barriers in traditional optical technologies, yielding revolutionary advances in traditional optical systems such as microscopes, telescopes and lithography systems.

Available in PDF, EPUB and Kindle. Book excerpt: In recent years, the field of silicon photonics has received much interest from researchers and companies across the world. The idea is to use photons to transmit information on a computer chip in order to increase computational speed while decreasing the power required for computation. To allow for communication between the chip and other components, such as the computer memory, these silicon photonics circuits need to be interfaced with optical fiber. Unfortunately, in order to interface an optical fiber with an integrated photonics circuit two major challenges need to be overcome: a mode-size mismatch as well as a polarization mismatch. While the problem of mode-size has been well investigated, the polarization mismatch has yet to be addressed. In order to solve the polarization mismatch one needs to gain control over the polarization of the light in a waveguide. In this thesis, I will present the components required to solve the polarization mismatch. Using a novel wave guiding structure, the hybrid plasmonic waveguide, an ultra-compact polarization rotator is designed, fabricated, and tested. The hybrid plasmonic rotator has a performance similar to purely dielectric rotators while being more than an order of magnitude smaller. Additionally, a broadband hybrid plasmonic coupler is designed and measured. This coupler has a performance similar to dielectric couplers while having a footprint an order of magnitude smaller. Finally, a system solution to the polarization mismatch is provided. The system, a polarization adapter, matches the incoming changing polarization from the fiber actively to the correct one of the silicon photonics circuit. The polarization adapter is demonstrated experimentally to prove its operation. This proof is based on dielectric components, but the aforementioned hybrid plasmonic waveguide components would make the system more compact.

Available in PDF, EPUB and Kindle. Book excerpt: Magnetic fields are responsible for much of the variability and structuring in the universe, but only on the Sun can the basic magnetic field related processes be explored in detail. While several excellent textbooks have established a diagnostic foundation for exploring the physics of unmagnetized stellar atmospheres through spectral analysis, no corresponding treatise for magnetized stellar atmospheres has been available. The present monograph fills this gap. The theoretical foundation for the diagnostics of stellar magnetism is developed from first principles in a comprehensive way, both within the frameworks of classical physics and quantum field theory, together with a presentation of the various solar applications. This textbook can serve as an introduction to solar and stellar magnetism for astronomers and physicists at the graduate or advanced undergraduate level and will also become a resource book for more senior scientists with a general interest in cosmic magnetic fields.

Book excerpt: Written by well-known scientists in the field with vast experience in teaching astrophotonics, this is the first book to bridge astronomy and photonics for the benefit of developing new astronomical instrumentation. The textbook is clearly structured and covers four main methods relevant to observational astronomy: adaptive optics, photometry, interferometry and spectroscopy. It follows a progressive didactical path in photonics, starting from fundamentals of wave- and micro-optics and developing step-by-step the formalisms required for the treatment of optical multilayers, fiber optics and diffraction/holographic gratings. This approach allows students with a physics/engineering background to learn about the problematic of observational astronomy, while, conversely, students of astronomy are exposed to topics in modern photonics. Each chapter is divided into three main sections devoted to the discussion of astronomical concepts required to size an instrument designed for the particular method, the photonic concepts that most suit that instrument, and an analysis of existing, related photonic instruments. A set of exercises and a bibliography complete each chapter. Appendices include a short review of fundamentals of wave optics and photon detectors, plus an overview of project design and management using a real-life example of an astronomical instrumentation project. With its review of the latest instrumentation and techniques, this is invaluable for graduate and post-graduate students in astronomy, physics and optical engineering.

Available in PDF, EPUB and Kindle. Book excerpt: Radiation from astronomical objects generally shows some degree of polarization. Although this polarized radiation is usually only a small fraction of the total radiation, it often carries a wealth of information on the physical state and geometry of the emitting object and intervening material. Measurement of this polarized radiation is central to much modern astrophysical research. This handy volume provides a clear, comprehensive and concise introduction to astronomical polarimetry at all wavelengths. Starting from first principles and a simple physical picture of polarized radiation, the reader is introduced to all the key topics, including Stokes parameters, applications of polarimetry in astronomy, polarization algebra, polarization errors and calibration methods, and a selection of instruments (from radio to X-ray). The book is rounded off with a number of useful case studies, a collection of exercises, an extensive list of further reading and an informative index. This review of all aspects of astronomical polarization provides both an essential introduction for graduate students, and a valuable reference for practising astronomers.

Book excerpt: Optical Polarization in Biomedical Applications introduces key developments in optical polarization methods for quantitative studies of tissues, while presenting the theory of polarization transfer in a random medium as a basis for the quantitative description of polarized light interaction with tissues. This theory uses the modified transfer equation for Stokes parameters and predicts the polarization structure of multiple scattered optical fields. The backscattering polarization matrices (Jones matrix and Mueller matrix) important for noninvasive medical diagnostic are introduced. The text also describes a number of diagnostic techniques such as CW polarization imaging and spectroscopy, polarization microscopy and cytometry. As a new tool for medical diagnosis, optical coherent polarization tomography is analyzed. The monograph also covers a range of biomedical applications, among them cataract and glaucoma diagnostics, glucose sensing, and the detection of bacteria.
