Abstract:

Self-Electroopic Effect Device’s (SEED’s) basic structure and operation principles are proposed, then equivalent Resistance-Capacitance (RC) model are applied for analysis. Theoretical analysis and mathematic computation are utilized to obtain SEED’s Voltage-Time (V-T) characteristic expressions. Theoretical expressions are verified by simulations, and the simulations compare SEED’s switch characteristics with different radiuses of input control beams, and demonstrate that SEED’s switch characteristic can be effectively improved with small input radius. Moreover, the simulations compare SEED’s Voltage-radius (V-r) diffusion characteristics with a fixed time and different input radiuses, then the results reveal that SEED can only keep its excellent switch performance near the input light beam’s center.
