Theory of zero-birefringence multiple-quantum-well opticalwaveguides

摘要

Several types of multiple-quantum-well (MQW) optical waveguidesnare analyzed theoretically. We show that MQW waveguides in the form ofnridge, deep-ridge, and strip-loaded waveguides can be designed tonexhibit zero modal birefringence, and numerous such designs arenpossible. The effects of the physical parameters of the waveguides onnthe zero-birefringence conditions are highlighted with numericalnexamples. Zero-birefringence MQW waveguides are potentially useful fornforming polarization-insensitive MQW-based optoelectronic devices
