Silicon-on-Sapphire Waveguides: Mode-converting Couplers and Four-wave Mixing

Abstract

The goal of this project is to design and develop a widely tunable coherent light source in the wavelength range between 3 and 4 m via four-wave mixing in silicon-on-sapphire waveguides. This project will address the Navy need to extend the range of spectrum dominance. Previous investigations show that this spectral range is of interest for applications that include free-space communications, laser radar, optical countermeasures, and remote sensing. This document summarizes progress made during fiscal year 2014, and specifically includes: Design, fabrication, and performance of mode-converting couplers and silicon-on-sapphire waveguides. Measurements of four-wave mixing in silicon-on-sapphire waveguides.
