Analysis of response characteristics for polymer directional coupler electro-optic switches

Abstract: By using the coupled mode theory, electro-optic modulation theory, conformal transforming method, image method and the proposed transfer matrix technique, novel expressions for the both cases of the low switching frequency and the ultra-high switching frequency are presented for analyzing the transmission powers, rise time, fall time, switching time and switching frequency of the polymer directional coupler electro-optic switches. Simulation results of an application based on the technique show that, the switching voltage and coupling length are about 1.457V and 4.374mm, respectively, and the switching time and cutoff switching frequency are about 32.8ps and 114.7GHz, respectively, for the designed switch.
