In order to utilize the large electro-optic coefficient of organic ionic crystal, 4-(4-dimethylaminostyryl)-1-methylpyridinium tosylate (DAST), a photobleaching technique was used for serially grafted DAST crystal waveguide fabrication. To fabricate a low optical loss crystal waveguide, a single-mode serially grafted DAST waveguide model with taper structure has been designed and simulated by beam propagation method (BPM). For the single-mode serially grafted crystal waveguide fabrication, we developed a novel single thin crystal growth method successfully. An attempt for the waveguide fabrication has been carried out. A feasible method for the single-mode crystal waveguide fabrication was proposed.
