Abstract
An example optical system having an optical supply sub-system for supplying light to a photonic integrated circuit is presented. The optical supply sub-system includes a primary light source, an auxiliary light source, a first optical coupler, and a second optical coupler. The first optical coupler includes a first metal-oxide-semiconductor capacitor microring resonator (MOSCAP MRR) and the first optical coupler includes a second MOSCAP MRR. The first optical coupler is coupled to the primary light source and the photonic integrated circuit to control the propagation of the primary light to the photonic integrated circuit. The auxiliary light source may be configured to generate an auxiliary light when the primary light source malfunctions and the first MOSCAP MRR and the second MOSCAP MRR are controlled to control propagation of the auxiliary light from the auxiliary light source to the photonic integrated circuit.
