Paper Abstract

A structure in photonic integrated circuit with a microring serially connected by an optical attenuator is proposed to generate the non-reciprocity by the nonlinear optical effect in microring. We find that when the information of the transmission spectra of both forward and backward directions is utilized for sensing, the precision of sensing can be enhanced. We calculate the non-reciprocity ratio of our proposed structure, and utilize this spectrum for sensing. Simulation shows the non-reciprocal spectrum varies with the attenuation value of the attenuator. The slope of 4.34dB/GHz can be achieved by utilizing 10dB attenuator, and the sensing frequency range is 7.35GHz. These results benefit its application in sensing.
