Download or read book Photonic Band Gap Structures as a Gateway to Nano Photonics written by and published by . This book was released on 1999 with total page 13 pages. Available in PDF, EPUB and Kindle. Book excerpt: This LDRD project explored the fundamental physics of a new class of photonic materials, photonic bandgap structures (PBG), and examine its unique properties for the design and implementation of photonic devices on a nano-meter length scale for the control and confinement of light. The low loss, highly reflective and quantum interference nature of a PBG material makes it one of the most promising candidates for realizing an extremely high-Q resonant cavity,>10,000, for optoelectronic applications and for the exploration of novel photonic physics, such as photonic localization, tunneling and modification of spontaneous emission rate. Moreover, the photonic bandgap concept affords us with a new opportunity to design and tailor photonic properties in very much the same way we manipulate, or bandgap engineer, electronic properties through modern epitaxy.

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.

Download or read book Novel Nanophotonic Structures and Devices for Optical Interconnect and Lithography Applications written by Jun Tan and published by . This book was released on 2013 with total page 92 pages. Available in PDF, EPUB and Kindle. Book excerpt: Silicon photonics witnessed spectacular progress in the past decade. Optical interconnects, low cost telecommunications and optical sensors are three main application areas. Photonic crystal is composed of periodic scatterers. When the scatterers are of the proper size and the periodicity is on the order of wavelength, all the reflections and refractions will cancel, forming photonic band-gap forbidding light to penetrate into it. If we remove one line of the scatterers, the light will be confined in this "wire" tightly, forming a photonic crystal waveguide (PCW). To date, most of the PCW research has been focused on the even TE-like mode. However, a PCW often has an odd TE-like mode inside the photonic band gap exhibiting the slow-light effect as well. We demonstrated a novel scheme to control the excitation symmetry for a slow-light odd-mode in a PCW, and investigated the spectral signature. An odd-mode Mach-Zehnder coupler was introduced to excite a high-purity odd-mode with 20 dB signal-to-background contrast. Assisted by a mixed-mode Mach-Zehnder coupler, slow-light mode-beating can be observed, and determine the group index of this odd-mode. With slow-light enhancement, this odd-mode can help enable miniaturized devices based on transforming mode symmetry. The evolution of the transmission spectrum of a PCW under electro-optic tuning was studied in the band of an odd TE-like mode. The spectral signature of the interband scattering from the TM-like mode to the odd TE-like mode was characterized at various bias levels. The shift of the odd-mode band was determined. Simulations were performed to explain the spectral shift based on electro-optic and thermo-optic effects in the active photonic crystal structures. Potential impact of interband scattering on indirect interband-transition-based optical isolators is discussed and potential remedies are offered. Nanopatterning is one of the key steps in nano-fabrication. We applied the negative index material (NIM) to enhance the evanescent wave in the near-field region and excite surface plasmons. Superlens devices working at 193nm DUV wavelength were fabricated, imaged on the photoresist, and characterized by AFM. A series of Finite-difference time-domain (FDTD) simulations were performed to analyze the imaging mechanism of the superlens.

Book excerpt: This comprehensive text collects the progress made in recent years in the fabrication, processing, and performance of organic nanophotonic materials and devices. The first part of the book addresses photonic nanofabrications in a chapter on multiphoton processes in nanofabrication and microscopy imaging. The second part of the book is focused on nanoscale light sources for integrated nanophotonic circuits, and is composed of three chapters on organic nano/microcavities, organic laser materials, and polymer light-emitting electrochemical cells (LECs). The third part is focused on the interactions between light and matter and consists in three chapters, including the propagation of light in organic nanostructures and photoswitches based on nonlinear optical polymer photonic crystals and photoresponsive molecules, respectively. The final chapter of this book introduces the integration of miniaturized photonic devices and circuits with various organic nanophotonic elements. The practical case studies demonstrate how the latest applications actually work, while tables throughout the book summarize key information and diagrams and figures help readers to grasp complex concepts and designs. The references at the end of each chapter can be used as the gateway to the relevant literature in the field. Moreover, this book helps researchers to advance their own investigations to develop the next generation of miniaturized devices for information processing, efficient energy conversion, and highly accurate sensing.
