Semiconductor optical switch |
摘要 |
A semiconductor optical switch may include an optical waveguide, a first electrode, and a first reflector. The optical waveguide may include a branching point, a first incoming path and first and second outgoing paths. The first electrode is provided at the branching point to give carrier injection into the branching point to allow that the branching point reflects an optical signal that is propagating through the first incoming path so that the reflected optical signal propagates through the second outgoing path. The first electrode may give no carrier injection into the branching point to allow that the branching point allows the optical signal to transmit through the branching point and propagate through the first outgoing path. The first reflector is provided on the first outgoing path. The first reflector reflects a leakage of light that has propagated from the branching point.
