摘要: The technology and performances of a micromachined channel waveguides, based on PECVD deposition silicon oxynitride (SiOxNy) thin films, is presented. parameters the process are studied in connection with their optical, mechanical chemical properties. Waveguide deign optimized allowing single mode, low loss propagation high efficiency coupling mode optical fiber. proposed applied to fabricate pigtailed Mach-Zehnder interferometers, where from fiber waveguide etch U-grooves, supporting fibers same substrate as substrate.
