Hybrid laser source with ring-resonator reflector
A laser source includes a semiconductor optical amplifier (SOA) as a gain medium that receives and amplifies an optical signal characterized by at least a wavelength associated with a lasing mode of the laser source. This laser source includes a first optical waveguide and a second optical waveguide optically coupled to the SOA. Furthermore, a wavelength-selective reflector is optically coupled to the first optical waveguide and the second optical waveguide, where a closed loop defined by the SOA, the first optical waveguide, the wavelength-selective reflector and the second optical waveguide defines a cavity of the laser source.
