| 英文摘要 | An optical switch includes a semiconductor substrate having a surface, a ridge waveguide disposed on the surface of the semiconductor substrate and including an optical waveguide layer having an MQW structure, first and second cladding layers sandwiching the optical waveguide layer, and a switch disposed in a part of the ridge waveguide. A part of the MQW optical waveguide layer included in the switch is thicker than the other part of the optical waveguide layer, whereby the energy band gap of the optical waveguide layer of the switch is smaller than the energy band gap of the other part of the optical waveguide layer and larger than the energy of the signal light. Therefore, the absorption loss of the signal light traveling through the optical waveguide layer is reduced. Furthermore, since the variation in the refractive index of the switch when current is applied to the switch is increased, the ON/OFF ratio of the switch is increased. |
