Abstract
We have successfully fabricated a serially grafted waveguide combining a ty pe of organic nonlinear optical (NLO) crystal, 4-(p-dimethylaminostyryl)-1- methylpyridinium tosylate (DAST), and a transparent polymer. To utilize the large electrooptic coefficient of the DAST effectively, a waveguide struct ure is desirable, Since organic crystals with large NLO effects show large optical losses, a major part of this serially grafted waveguide was compose d of the transparent polymer. The input/output optical beam has been effect ively coupled to the DAST crystal waveguide through the transparent polymer waveguide. This serially grafted structure is a potential candidate for fa bricating many types of practical devices with optical nonlinearity such as the Mach-Zehnder interferometer(MZI).
