Fabrication, Characterization, and Analysis of Zinc-Diffused GaAs Waveguides

IEEE Journal of Quantum Electronics, Volume 25, No. 5, Year 1989

GaAs planar channel waveguides are Fabricated with diffused boundaries using a zinc-doped spin-on-glass source. Low-loss (∼1.9 dB/cm) single-mode waveguides are achieved. Modal properties of the waveguides are experimentally investigated. A simple model is used to analyze the waveguides. © 1989 IEEE
