【Abstract】 A microring array model for electro-optic switch was proposed in the paper. When the working wavelength was 1 550 nm,and the operating voltage was applied on microring i in turn for the cascade structure of 4 microrings and 5 channels,the output light power of channel i increased and then became saturated very fast with an increase in the operating voltage. Simulation results for the designed device showed that the insertion loss was 1. 3 ～ 4. 5 dB and the crosstalk was less than-8. 0 d B when the switching voltage was 7. 5 V.更多还原
