摘要	PURPOSE:To attain high-speed response, small-sized constitution and high reliability by forming waveguide optical switches connected like a tree and actuated by an electrooptical effect. CONSTITUTION:Light 11 incident on an input optical waveguide 2a is reflected by the 1st (81) waveguide optical switch 2, outputted to a waveguide 2c and then guided to an input optical waveguide of the 2nd (82) waveguide optical switch 2'. The light is straightly guided by the waveguide optical switch 2', guided to an input optical waveguide 26a of the 3rd (83) waveguide optical switch 2'' by an optical waveguide 36 through an optical waveguide 26a, reflected by the waveguide optical switch 2'' and outputted to an optical waveguide 26b to obtain output light 12. When light is inputted to the waveguide 26b, the light is outputted from the optical waveguide 2a. Thus, an I/O optical waveguide can be connected to one O/I optical waveguide out of 2 O/I optical waveguides in accordance with the state (lambda1, lambda2, lambda3)=(a1, a2, a3) of control light. Namely electromagnetically induced noise can be prevented by connecting the waveguide optical switches like a tree on the same substrate and attaining high-speed response, small-sized constitution and high reliability and performing control through light.
其他摘要	目的：通过形成连接成树状并由电光效应驱动的波导光开关，实现高速响应，小尺寸构造和高可靠性。构成：入射到输入光波导2a上的光11被第一（81）波导光开关2反射，输出到波导2c，然后被引导到第二（82）波导光开关2'的输入光波导。光由波导光开关2'直接引导，通过光波导36通过光波导26a引导到第三（83）波导光开关2“的输入光波导26a，由波导光开关2反射“，并输出到光波导26b以获得输出光12.当光输入到波导26b时，光从光波导2a输出。因此，根据（3）的状态（λ1，λ2，λ3）=（a1，a2，a3），I / O光波导可以连接到2 3 O / I个光波导中的一个O /控制灯。即，通过在同一基板上连接诸如树的波导光开关，并获得高速响应，小尺寸构造和高可靠性并通过光进行控制，可以防止电磁感应噪声。
