Abstract:
An integrated laser that provides multiple outputs includes a reflective silicon optical amplifier (RSOA) having a reflective end with a reflective coating and an interface end. It also includes an optical waveguide optically coupled to the RSOA. A distributed-Bragg-reflector (DBR) ring resonator is also optically coupled to the optical waveguide, wherein the DBR ring resonator partially reflects a wavelength of the optical signal from the optical waveguide, thereby causing balanced light to flow in clockwise and counter-clockwise directions inside the DBR ring resonator. The integrated laser additionally includes an output waveguide having 2*N ends that function as two outputs, wherein the output waveguide is optically coupled to the DBR ring resonator, which causes balanced light to flow in two directions in the output waveguide, thereby causing the 2*N outputs to provide balanced power.
