Description The properties of semiconductor-clad optical waveguides based on glass substrates were investigated. Computer modeling studies on four-layer silicon-clad planar dielectric waveguides indicated that the attenuation and mode index should behave as exponentially damped sinusoids as the silicon thickness is decreased below one micrometer. A variety of techniques have been proposed for fabricating integrated optical devices using semiconductors, lithium niobate, and glasses as waveguides and substrates. The use of glass waveguides and their interaction with thin semiconductor cladding layers was studied. Though the interactions of these multilayer waveguide structures have been analyzed here using glass, they may . Investigation of semiconductor clad optical waveguides. By R. F. Carson and T. E.

Keywords: Silicon-clad waveguide, TE/TM pass polarizer, extinction ratio, Transfer matrix method. I. Introduction Multilayer waveguides are used in the implementation of variety of optical devices including modulators, waveguide polarizers, semiconductor lasers, Bragg reflectors, directional couplers and . Planar optical waveguides consisting of thin dielectric films with metal cladding have been investigated theoretically and experimentally. A computer program was devised to provide the phase and attenuation constants and wavefunctions for TE and TM modes in symmetric and asymmetric guides. Approximate expressions suitable for slide-rule calculation were also derived. Semiconductor Optoelectronics (Farhan Rana, Cornell University) Chapter 8 Integrated Optical Waveguides Dielectric Slab Waveguides Introduction: A variety of different integrated optical waveguides are used to confine and guide light on a chip. The most basic optical waveguide is a slab waveguides shown below. 1 April Design of silicon waveguides with all-dielectric metamaterial cladding by Andraž Debevc, Janez Krč, and Marko Topič "Design of silicon waveguides with all-dielectric metamaterial cladding by employing numerical simulations", Proc Coupling And Absorption Phenomena In Semiconductor-Clad Dielectric Optical Waveguides.
Semiconductor optical waveguides are a very important part of modern integrated optoelectronic systems, especially for electrically active devices. Applications range from semiconductor lasers, optical filters, switches, modulators, isolators, and photodetectors. An investigation study concerning optical fiber alignment and micro-mirror performance in MOEMS devices is being reviewed in this paper. The central attention of the study is the analysis of optical fibers positioning, alignment, bonding, optical improvements, coupling to micro-lenses for beam collimation and waveguides. Also, we highlight features. INVESTIGATION OF OPTICAL LOSS CHANGES IN SILOXANE POLYMER WAVEGUIDES DURING THERMAL CURING AND AGING A Dissertation Presented to The Academic Faculty by Shashikant G. Hegde In Partial Fulfillment of the Requirements for the Degree Doctor of Philosophy in the G.W. Woodruff School of Mechanical Engineering Georgia Institute of Technology April A hybrid group IV ridge waveguide platform is demonstrated, with potential application across the optical spectrum from ultraviolet to the far infrared wavelengths. The waveguides are fabricated by partial etching of sub-micron ridges in a nanocrystalline diamond thin film grown on top of a silicon wafer. To create vertical confinement, the diamond film is locally undercut by exposing the chip.
