Download or read book Subpecosecond All Optical Switching in a Polymeric One-dimensional Photonic Crystal written by Michael Yang and published by . This book was released on 2006 with total page 93 pages. Available in PDF, EPUB and Kindle. Book excerpt: "All optical switching is one of potential candidate that may break the computational limit based on semiconductor technology. Such a device has the advantage of lower power dissipation, subpicosecond switching time, and holographic processing. One way of realizing such a device is to exploit the high reflectivity of one-dimensional Bragg reflection. High reflection of the input probe beam is achieved by properly fabricating the photonic crystal with alternating layers with appropriate thicknesses and refractive index in order to satisfy the Bragg condition for high reflections. By using highly nonlinear optical material as one of the layers in the Bragg reflection stack, a pumping beam can be used to alter the refractive index of the nonlinear material, and thereby failing to satisfy the Bragg condition, so the transmission of the input probe beam is changed. Three one-dimensional photonic crystals were fabricated. They differs primarily by its physical geometry in effort to boost the switching state intensity. All three takes the advantage of high non-linear absorption poly(thiophene). The first photonic crystal was based solely on poly(thiophene), while the second one incorporates a non-linear Bragg reflector. By taking advantage of the strong angle dependence of the photonic crystal, the crystal was fabricated into a domed shaped geometry in order to further enhance the distinction of the two switch states. Probe-pump setup was used to determine the bistability of each of the photonic crystal. The transmission of the probe beam intensity change between the two switch state controlled by the pumping beam at pumping power of 3.64 (plus or minus) 0.04 GW/cm2 was 4.19 (plus or minus) 0.24 MW/cm2. Femtosecond pump-probe VIS transient spectroscopy was used to determine the transient responses of each of the photonics crystals. All of the crystals exhibit less than 250 fs rise peak-to-peak time. However, the decay time were much longer and only achieve subpicosecond times when the intensity decreased to 50% of its peak-to-peak value."--abstract.

This book was released on 2012-12-06 with total page 537 pages. Available in PDF, EPUB and Kindle. Book excerpt: Photonics is being labelled by many as the technology for the 21st century. Because of the structural flexibility both at the molecular and bulk levels, organic materials are emerging as a very important class of nonlinear optical materials to be used for generating necessary nonlinear optical functions for the technology of photonics. Since the last NATO advanced research workshop on "Polymers for Nonlinear Optics"held in June 1988, at Nice - Sophia Antipolis, France. there has been a tremendous growth of interest worldwide and important development in this field. Significant progress has been made in theoretical modeling, material development, experimental studies and device concepts utilizing organic materials. These important recent developments provided the rationale for organizing the workshop on "Organic Materials for Nonlinear Optics and Photonics" which was held in La Rochelle, France, in August 1990. This proceeding is the outcome of the workshop held in La Rochelle. The objective of the workshop was to bring together scientists and engineers of varied backgrounds working in this field in order to assess the current status of this field by presenting significant recent developments and make recommendations on future directions of research. The workshop was multidisciplinary as it had contributions from chemists, physicists, materials scientists and device engineers. The participants were both from industries and universities.

Available in PDF, EPUB and Kindle. Book excerpt: This treatise is a compendium of papers based on invited talks presented at the American Chemical Society Symposium on Electroactive Polymers which covered nonlinear optical polymers and conducting polymers, the common denominator being the correlated pi-electron structures. The improved understanding of the consequences of pi-electron delocalization upon nonlinear optical properties and charge carrier dynamics has laid the foundation for the rapid development and application of the electroresponse of conjugated polymers. As a result, the area of electroactive and nonlinear optical polymers is emerging as a frontier of sCience and technology. It is a multidisciplinary field that is bringing together scientists and engineers of varied background to interface their expertise. The recent explosion of interest in this area stems from the prospect of utilizing nonlinear optical effects for optical switching and logic operations in optical computing, optical signal processing, optical sensing and optical fiber communications. Polymers and organic are rapidly becoming one of the major material classes for nonlinear optical applications along with multiple quantum wells, ferroelectrics and other oxides, and direct band-gap semiconductors. The reasons for this lie in the unique molecular structures of polymers and organics and the ability to molecularly engineer the architecture of these structures through chemical synthesis.

Available in PDF, EPUB and Kindle. Book excerpt: We have developed two experimental techniques for creating photonic structures in nonlinear optical (NLO) polymers with precisions down to nanoscale. The first technique uses nanoimprinting technology to directly pattern the guest-host NLO polymers. It can be applied to the fabrication of photonic bandgap structures in NLO materials, as well as many other photonic structures in both linear and nonlinear polymers. For example, we have shown that micro-ring optical resonator structure can be fabricated by using the imprinting technique. The second technique utilize self-assembly of NLO polymer monolayers onto nanostructured template. This approach provides a highly effective means to implement waveguide devices using high performance self-assembled polymers with large electro-optic activity and inherent long-term stability. Such method can also be extended to Langmuir-Blodgett (LB) and covalently self-assembled thin films, and enables practical device applications for nonlinear optical thin films synthesized by these different layer-by-layer growth approaches to utilize their material properties, such as high nonlinear optical coefficient, very fast electronic response and good thermal and temporal stability.
