Abstract

We have successfully fabricated a serially grafted waveguide combining a type 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 structure is desirable. Since organic crystals with large NLO effects show large optical losses, a major part of this serially grafted waveguide was composed of the transparent polymer. The input/output optical beam has been effectively coupled to the DAST crystal waveguide through the transparent polymer waveguide. This serially grafted structure is a potential candidate for fabricating many types of practical devices with optical nonlinearity such as the Mach-Zehnder interferometer(MZI).
