Design and Investigation on Characteristics of a Semiconductor Micro-Ring Laser with Retro-Reflector Cavity

Abstract:

A miniaturized semiconductor micro-ring laser with retro-reflector cavity is investigated. By introducing higher order aspheric terms, miniaturized parabolic mirrors are designed and optimized. A Retro-Reflector based semiconductor micro-ring laser with equivalent radius of 38μm and low threshold current of 60mA is realized. The free-running wavelength is 1541.04 nm when the injection current is increased to 140mA.
