Optical module, light divider/insertor and light transmission device

摘要

An optical module has a planar waveguide which is provided with an optical circuit for an optical switch formed by 2x2 cross optical waveguides A1 to D1 and an optical circuit for an optical variable attenuator formed by 2x2 cross optical waveguides A2 to D2. Joined onto the planar waveguide is an actuator structure and the actuator structure is constituted by an actuator section for an optical switch and an actuator section for an optical variable attenuator. The optical circuit of the planar waveguide and the actuator section constitute an optical switch, whereas the optical circuit of the planar waveguide 2 and the actuator section constitute an optical variable attenuator.
