Book Description
To fully utilize the advances of electro-optic (EO) polymer research, a detail design and model of a triple stacked poled-polymer, electro-optic waveguide modulator was developed to provide guidance in the selection of cladding layers and demonstrate how the mode conditions affect the overall device performance. Waveguide devices depend not only on the EO materials used in the core, but also on the cladding materials. In contrast to most of the research that has focused on molecular engineering of the electro-optically active materials to improve the core properties of the waveguide, this work studied the effects of cladding material properties to improve overall device performance of an electro-optic waveguide modulator. Various, commercially available polymer materials were identified and investigated for potential cladding layers according to their optical, electrical, process ability and film casting properties. A poled-polymer, strip-loaded waveguide, EO modulator is designed and analyzed in terms of single mode conditions, optical loss due to the metal electrodes, modulation efficiency, and mode size. Two designs were compared: Design 1 optimized the half-wave voltage for a single-arm modulator (Vpi = 2.5 V) with a nearly symmetric waveguide by maximizing modulation efficiency and minimizing the overall thickness of the waveguide; Design 2 optimized the insertion loss (6 dB) with a strongly asymmetric waveguide by maximizing the overall mode size to most efficiently overlap with a single mode fiber. High frequency analysis of a microstrip electrode showed a modulator with a push-pull scheme can be fabricated with half-wave voltage (Vpi) of 4.0 V for Design 1 and 5.1 V for Design 2 at 3 GHz. Some general guidelines in the design of a poled-polymer electro-optic modulator incorporating a strip-loaded waveguide structure are suggested. First, the core layer thickness and ridge width supporting single mode propagation should be fabricated as large as possible by increases the asymmetry of the refractive index between the top and bottom cladding layer. Second, the thicknesses of the top and bottom cladding layers must be optimized through an analysis of the waveguide mode amplitude distribution so that the electrode-associated optical loss is minimized to a required level while simultaneously the total thickness of the waveguide is minimized. The ridge structure greatly simplifies fabrication procedures, reduces fabrication steps and eliminates propagation losses due to roughness of etched sidewalls. The results of the analysis were modeled in beam propagation software to confirm the ideal conditions for single mode propagation.

Book Description
The introduction of GaAs/ AIGaAs double heterostructure lasers has opened the door to a new age in the application of compound semiconductor materials to microwave and optical technologies. A variety and combination of semiconductor materials have been investigated and applied to present commercial uses with these devices operating at wide frequencies and wavelengths. Semiconductor modulators are typical examples of this technical evolutions and hsve been developed for commercial use. Although these have a long history to date, we are not aware of any book that details this evolution. Consequently, we have written a book to provide a comprehensive account of semiconductor modulators with emphasis on historical details and experimantal reports. The objective is to provide an up-to-date understanding of semiconductor modulators. Particular attention has been paid to multiple quantum well (MQW) modulators operating at long wavelengths, taking into account the low losses and dispersion in silica fibers occuring at around 1.3 and 1.55 mm. At the present time, MQW structures have been investigated but these have not been sufficiently developed to provide characteristic features which would be instructive enough for readers. One problem is the almost daily publication of papers on semiconductor modulators. Not only do these papers provide additional data, but they often modify the interpretations of particular concepts. Almost all chapters refer to the large number of published papers that can be consulted for future study.

Book Description
This straightforward text examines the scientific principles, characterization techniques, and fabrication methods used to design and produce high quality optical fibers. Polymer Fiber Optics: Materials, Physics, and Applications focuses on the fundamental concepts that will continue to play a role in future research and applications. This book documents the underlying physics of polymer fibers, particularly aspects of light interaction, and details the practical considerations for a broad range of characterization techniques used to investigate new phenomena. The book presents basic fabrication techniques and protocols that will likely remain useful as new advances address specific processing challenges. The author presents a fresh approach to standard derivations, using numerous figures and diagrams to break down complex concepts and illustrate theoretical calculations. The final chapters draw attention to the latest directions in research and novel applications, including photomechanical actuation, electro-optic fibers, and smart materials.

Book Description
Optivision has competed a Phase I STTR project with the objective of developing highly active, electro-optic (EO) polymers tailored for use in in-line fiber photonic devices. The specific Phase I tasks were: (1) Synthesize or obtain a quantity of "development" polymer. (2) Develop suitable processing and characterization methodologies. (3) Perform device level testing of EO polymers using a polymeric in-line fiber (PILF) structure. (4) Identify suitable nonlinear optical (NLO) chromophores for resonantly enhanced EO polymers. (5) Develop a synthesis strategy for novel highly active EO polymers to be produced during Phase II. (6) Perform a high level design of a device to be built during the Phase II effort. We have successfully completed all of these tasks. We have developed new EO polyquinoline materials specifically tailored for use in PILF structures and demonstrated the use of these polymers in actual PILF devices. The new polyquinolines incorporate chromophores with large UB values and red shifted absorption peaks, resulting in polymers with EO coefficients of approximately 30 pm/V at a wavelength of 1.3 micrometers.

Book Description
Interfaces in Particle and Fibre-Reinforced Composites: From Macro- to Nanoscale addresses recent research findings on the particle-matrix interface at different length scales. The book's main focus is on the reinforcement of materials by particles that can result in a composite material of high stiffness and strength, but it also focuses on how the particle interacts with the (matrix) material, which may be a polymer, biological-based material, ceramic or conventional metal. The different types of particle reinforced composites are discussed, as is load transfer at the particle-matrix interface. Readers will learn how to select materials and about particle structure. Significant progress has been made in applying these approaches, thus making this book a timely piece on recent research findings on the particle-matrix interface at different length scales. - Features wide coverage, from polymer, to ceramics and metal-based particulate composites - Structured in a logical order to cover fundamental studies, computer simulations, experimental techniques and characterization
