Book Description
Annealed proton exchange (APE) is an important technique for the fabrication of waveguides in LiNbO3 for electrooptic and nonlinear optical applications. Unannealed proton exchanged (PE) waveguides have step-like refractive index profiles and large extraordinary refractive index changes, but suffer from reduced electrooptic and nonlinear coefficients. Post-exchange annealing is necessary to produce single mode waveguides that exhibit electrooptic and nonlinear optical properties comparable to bulk LiNbO3 and low insertion loss in fiber optic applications. While the PE process is well-characterized, quantitative modeling of APE waveguides is much less well developed. In this paper we present measurements of the effective mode indices and fundamental mode profiles for APE waveguides subjected to a variety of exchange and annealing conditions in both x- and z-cut substrates, along with empirical models for the concentration-dependent diffusion coefficient and dispersion that allow accurate calculation of the refractive index profile for APE waveguides as a function of exchange depth and anneal time for wavelengths between 0.4 and 1.1 micrometer. The reduction of the nonlinear susceptibility in PE waveguides, measured by a reflected second harmonic generation technique, is also discussed.

Book Description
The object of this school, held at Cargese, Corsica (France) from August 12th to 24th 1991, was the presentation of the field of guided wave nonlinear optics in a comprehensive, coherent, and heuristic fashion. It seems appropriate that this school began with an historical introduction by Professor Nicolaas Bloembergen of Harvard, the acknowledged "father" of nonlinear optics, in general, and concluded with a round table discussion headed by Dr. Eric Spitz, the Scientific Director of a multinational electronics company interested in developing industrial applications of guided wave nonlinear optics. The lectures covered both the theoretical framework of the field and applications to basic scientific research, optical communications and technical instrumentation. Specific topics developed included materials for guided wave nonlinear optics, nonlinear interactions using integrated optical guides, nonlinear surface waves, solitons, fiber nonlinear optics, ultra-fast coupler switching as well as the related topic of fiber and integrated optical lasers and amplifiers. Lectures have also been devoted to squeezed states, chaos and strange attractors. The subjects covered by the school underlines one of the major ways in which this field has evolved over the past thirty some odd years. The path from the original experiments with materials requiring mega-watt power lasers to the recent developments in guided wave configurations using milliwatt power diode lasers is marked by the conjunction of ever improving fundamental scientific comprehension and continuing technological developments.

Nonlinear Optical and Photorefractive Properties of Periodically Poled Channel Waveguides in Lithium Niobate
Author: Ansgar HellwigNonlinear Optical Effects and Materials
Author: Peter GünterPublisher: Springer
ISBN: 3540497137
Category : Science
Languages : en
Pages : 550
Book Description
Describing progress achieved in the field of nonlinear optics and nonlinear optical materials, the Handbook treats selected topics such as photorefractive materials, third-order nonlinear optical materials and organic nonlinear optical crystals, as well as electro-optic polymers. Applications of photorefractive materials in optical memories, optical processing, and guided-wave nonlinear optics in hotorefractive waveguides are described. As light will play a more and more dominant role as an information carrier, the review of existing and new materials given here makes this a keystone book in the field.
Lithium Niobate Photonics
Author: James E. ToneyPublisher: Artech House
ISBN: 1608079244
Category : Technology & Engineering
Languages : en
Pages : 283
Book Description
This new resource presents the concepts, technologies, and design techniques for devices based on the electro-optic effect in lithium niobate. It bridges from the theory of photonics and electro-optics, to the practice of electro-optic device design and application. There is an emphasis on practical analysis using modern modeling tools. The book explains the fundamental physics of the electro-optic effect, classes of electro-optic materials, electro-optic properties of lithium niobate, and the physics and uses of ferroelectric domain inversion. Readers are also provided with the principles of operation, performance measures, and design considerations for the most common types of electro-optic devices: beam deflectors, intensity and phase modulators, including quasi-phased matched devices.
Compact Blue-Green Lasers

ISBN: 9780521521031
Category : Science
Languages : en
Pages : 540
Book Description
William Risk, Timothy Gosnell and Arto Nurmikko have brought together their diverse expertise from industry and academia to write the first fully comprehensive book on the generation and application of blue-green lasers. This volume describes the theory and practical implementation of three techniques for the generation of blue-green light: nonlinear frequency conversion of infrared lasers, upconversion lasers, and wide bandgap semiconductor diode lasers. In addition, it looks at the various applications that have driven the development of compact sources of blue-green light, and reflects on the recent application of these lasers in high-density data storage, color displays, reprographics, and biomedical technology. Compact Blue-Green Lasers is suitable for graduate-level courses or as a reference for academics and professionals in optics, applied physics, and electrical engineering.
