Abstract

We describe the effect of UV photobleaching of poled polymer and silica films and the application of UV photobleaching to waveguide–type optical devices. Disperse Red 1–doped poled polymer and silica films with large and stable second–order nonlinearity were used as nonlinear optical materials. We investigated the mechanism of UV photobleaching of poled films by the changes in absorption spectrum and nonlinearity and refractive index. Moreover, simple fabrication of both the channel waveguide and the x(2) diffraction grating based on UV photobleaching is demonstrated.
