This book was released on 2003-03-05 with total page 222 pages. Available in PDF, EPUB and Kindle. Book excerpt: The future of information technology requires ultra high speed processing and large data storage capacity. Since the electronics technology using semi conduc tors and inorganic materials is about to reach its limits, much current research is focused on utilizing much faster photons than electrons, namely photonics. To achieve any significant effect on the actual use of the science of photonics, devel opments of more efficient photonics materials, better optical property evaluations, manufacture of devices for system applications, etc. are the subjects which need to be explored. In particular, the development of photonics materials stands in the forefront of research as this constitutes the most pertinent factor with regard to the development of ultra high speed and large capacity information processing. In this respect, there has been continuous research on photo responsive materials through molecular structure design and architecture and the results so far are very promising as functions and performances are beginning to realize their high expectations. The two special volumes "Polymers for Photonics Applications" give authorita tive and critical reviews on up to date activities in various fields of photonic poly mers including their promising applications. Seven articles have been contributed by internationally recognized and they deal with, polymers for second and third order nonlinear optics, quadratic parametric interactions in polymer waveguides, electroluminescent polymers as light sources, photoreflective polymers for holo graphic information storage, and highly efficient two photon absorbing organics and polymers.

Available in PDF, EPUB and Kindle. Book excerpt: Electro-optic (EO) polymers are an attractive alternative to inorganic nonlinear materials. EO polymers with a Pockel's coefficient, r33, greater than 320 pm/V have been recently demonstrated. In addition to their high EO activity, EO polymers have the additional benefit that their dielectric constants at optical and millimeter wave frequencies are closely matched which allow for bandwidths which are limited only by the resistive losses of traveling wave electrodes. The amorphous nature of the host polymer makes heterogeneous integration of the materials on any substrate possible. The devices which will have the most immediate impact based on these recent materials developments are EO waveguide modulators. Performance benchmarks of less than 6 dB insertion loss, sub-volt Vpi and greater than 100 GHz bandwidth have been achieved separately however, the challenge of achieving all of these benchmarks in a single device has not yet been met. The aim of this dissertation is to optimize passive materials to achieve efficient in device poling of EO polymers, optimize the chromophore loading of the active polymers and to optimize waveguide modulators for device performance within a particular system, analog RF photonic links. These optimizations were done by defining figures of merit for the materials and modulators. This research strategy has led to significant improvements in poling efficiency as well as modulators with record low insertion losses which maintain a low half-wave voltage; on the order of 1 - 2 Volts. Using this optimization strategy and state of the art EO polymers, devices which meet or surpass the benchmark performance values in all categories are expected in the near future.

Download or read book Frontiers in Polymer Research written by Robert K. Bregg and published by Nova Publishers. This book was released on 2006 with total page 288 pages. Available in PDF, EPUB and Kindle. Book excerpt: Polymers are substances containing a large number of structural units joined by the same type of linkage. These substances often form into a chain-like structure. Starch, cellulose, and rubber all possess polymeric properties. Today, the polymer industry has grown to be larger than the aluminium, copper and steel industries combined. Polymers already have a range of applications that far exceeds that of any other class of material available to man. Current applications extend from adhesives, coatings, foams, and packaging materials to textile and industrial fibres, elastomers, and structural plastics. Polymers are also used for most composites, electronic devices, biomedical devices, optical devices, and precursors for many newly developed high-tech ceramics. This book presents leading-edge research in this rapidly-changing and evolving field.
Download or read book High Voltage Poling of a Bulk Sample of Disperse Red 1 Polymethylmethacrylate Guest Host Polymer for U S Army Electro optical Applications written by and published by . This book was released on 2008 with total page 9 pages. Available in PDF, EPUB and Kindle. Book excerpt: Much attention has been paid in recent years to poling thin-film doped polymers for electro-optics applications, mostly in the area of telecommunications switching devices. However, there are applications where a larger thickness of guest-host polymer results in enhanced performance of the electro-optic device, such as in terahertz (THz) generation. The thicker path length available in bulk poled polymers will allow for improved THz power, sensitivity and signal-to-noise ratio in both THz generators and detectors. Large area Pockels cells constructed from electro-optic (EO) guest-host polymers have uses as high speed modulators and shutters, and any application requiring a large d33 or r33 will potentially benefit from bulk-poled guest-host polymer systems. For large-aperture applications, the optical path length is longer and both poling and operating fields must still be transverse to the direction of light propagation which presents a tremendous challenge in building devices. Given the limitations of thin-film poling for fabricating large-aperture devices, the fabrication of a thick EO polymer slab with the proper orientation is an important goal. Our proposed solution is to pole a thick slab, cut, polish and re-orient 90 degrees. As a first step towards testing our proposed solution, we describe for the first time the fabrication and poling of a 700 micrometer thick bulk piece of polymethylmethacrylate (PMMA) doped with various concentrations of Disperse Red 1 (DR1). Maker fringe analysis will demonstrate that under the poling fields currently available to us (57 V/micrometer to 71 V/micrometer), that substantial ordering of the DR1 chromophores is occurring, resulting in birefringence and significant d33 and r33 values.

Download or read book Beam Shaping and Control with Nonlinear Optics written by F. Kajzar and published by Springer Science & Business Media. This book was released on 2006-04-11 with total page 479 pages. Available in PDF, EPUB and Kindle. Book excerpt: The field of nonlinear optics, which has undergone a very rapid development since the discovery of lasers in the early sixties, continues to be an active and rapidly developing - search area. The interest is mainly due to the potential applications of nonlinear optics: - rectly in telecommunications for high rate data transmission, image processing and recognition or indirectly from the possibility of obtaining large wavelength range tuneable lasers for applications in industry, medicine, biology, data storage and retrieval, etc. New phenomena and materials continue to appear regularly, renewing the field. This has proven to be especially true over the last five years. New materials such as organics have been developed with very large second- and third-order nonlinear optical responses. Imp- tant developments in the areas of photorefractivity, all optical phenomena, frequency conv- sion and electro-optics have been observed. In parallel, a number of new phenomena have been reported, some of them challenging the previously held concepts. For example, solitons based on second-order nonlinearities have been observed in photorefractive materials and frequency doubling crystals, destroying the perception that third order nonlinearities are - quired for their generation and propagation. New ways of creating and manipulating nonl- ear optical materials have been developed. An example is the creation of highly nonlinear (second-order active) polymers by static electric field, photo-assisted or all-optical poling. Nonlinear optics involves, by definition, the product of electromagnetic fields. As a con- quence, it leads to the beam control.
