Abstract :
An optical module for demultiplexing optical communication wavelengths is realized by incorporating a multilayer filter into a light-induced self-written (LISW) optical waveguide. For the purpose, a 24-layer-filter comprising low and high refractive index hybrid material layers is designed and fabricated by mutual spin-coating and UV-curing. The LISW waveguide by exposure to 850-nm light using bi-directional process to a photocurable resin is realized, and insertion loss difference reaches to 17.8 dB between 1.31 μm and 1.55 μm.
