Abstract
A photonic integrated circuit (PIC) comprises an optical switch, a plurality of input edge couplers comprising a first input edge coupler and coupled to the optical switch, a plurality of input surface grating couplers (SGCs) comprising a first input SGC and coupled to the optical switch, a plurality of output edge couplers comprising a first output edge coupler and coupled to the optical switch, and a plurality of output SGCs comprising a first output SGC and coupled to the optical switch. A method of fabricating a PIC comprises patterning and etching a silicon substrate to produce a first optical switch, a first surface grating coupler (SGC) coupled to the first optical switch, and a first edge coupler coupled to the first optical switch.
