Spectral Characteristics of an InP-Based Semiconductor Laser With Fully Coupled Straight-Ridge and Racetrack Waveguides

Integrated semiconductor lasers are important for optical communications, gas sensing, biomedicine, and related fields. Conventional devices are commonly fabricated by dry etching, where sidewall roughness and surface defects may affect scattering and waveguide losses. In this work, we propose and fabricate an InP-base...
