Abstract

Abstract: A temperature sensor using cascaded microring resonator based on frequency beat system is presented and simulated in this paper. By changing bending radius of the inner ring, the relations between it and resonator wavelength spacing have been theoretically simulated. The simulation results show that the resonator frequencies of small microring transform to two frequencies and interval of these frequencies is very small which show this structure can be used as a sensor detector in beat frequency sensing system. Considering the thermal-optical effect of silicon, by changing the temperature, the output spectrum response is analysed in optical and microwave regime. The sensitivity is 7.2MHz/K.
