PROBLEM TO BE SOLVED: To provide an optical waveguide switch capable of reducing a driving voltage and shortening a total length. SOLUTION: The optical waveguide switch 10 has a structure where cores 6 and 7 made of electric optical polymers are brought into contact with both sides of a core 4 made of a sol-gel glass in an in-plane direction DR2 of a substrate by a tapered structure. The clad 5 of a directive coupling mutual operation area made of an electric optical polymer is disposed so as to be brought into contact with the cores 4, 6, and 7. The core 4, the cores 6 and 7, and the clad 5 have refractive indexes of 1.5, 1.632, and 1.630, respectively. The cores 4, 6, and 7 and the clad 5 are surrounded with a clad 3. Electrodes 13 and 14 are respectively disposed for applying voltages to the cores 6 and 7 brought into contact with the clad 5. The optical waveguide switch 10 emits guide light from the core 6 or the core 7 by controlling application/non-application of voltages to the electrodes 13 and 14. COPYRIGHT: (C)2010,JPO&INPIT |
