| 摘要 |
A photonic integrated circuit (PIC) (600) comprises an optical switch (650), a plurality of input edge couplers (620) comprising a first input edge coupler (620) and coupled to the optical switch (650), a plurality of input surface grating couplers (SGCs) (630) comprising a first input SGC (630) and coupled to the optical switch (650), a plurality of output edge couplers (620) comprising a first output edge coupler (620) and coupled to the optical switch (650), and a plurality of output SGCs (630) comprising a first output SGC (630) and coupled to the optical switch (650). A method (1100) of fabricating a PIC (600) comprises patterning and etching a silicon substrate to produce a first optical switch (650), a first surface grating coupler (SGC) (630) coupled to the first optical switch (650), and a first edge coupler (620) coupled to the first optical switch (650). |
