Abstract:
A semiconductor device, comprising:a substrate made of a semiconductor material;an active semiconductor medium formed on said substrate and configured to produce photons in response to an energizing input;a first semiconductor cladding layer formed on a first side of said active semiconductor medium and in contact with said active semiconductor medium;a second semiconductor cladding layer formed on a second opposing side of said active semiconductor medium and in contact with said active semiconductor medium, said first and second cladding layers configured to confine said photons within said active semiconductor medium;a wave-guiding element configured to guide optical waves and disposed on said first side of said active semiconductor medium, said wave-guiding element having a grating which is operable to reflect an optical wave at a specified wavelength that satisfies a phase-matching condition of said grating; andan optical reflector formed on said second side of said active semiconductor medium such that said optical reflector and said grating in said wave-guiding element forms an optical cavity with a cavity optic axis substantially perpendicular to said first and second cladding layers, and said active semiconductor medium.
