In the present report, a photonic crystal based micro-ring resonator (MRR) structure is proposed which is very compact in size and has very fast response and is employed for temperature sensing purpose. Temperature sensing application for both the single MRR and cascaded MRR is illustrated in this paper. The sensitivity of the reported structure is increased from 2.9 nm/°C to 3.4 nm/°C by cascading two MRR. The refractive index of the material is subjected to change with the variation in temperature which results in the shift of the resonant wavelength of the proposed sensor. The finite difference time domain (FDTD) simulation is utilized to see the transmission spectrum of the proposed structure and analyzing the shift in the resonance wavelength the temperature is calculated. The proposed design is simple, reliable and may be integrated into different transducer and sensing applications.

在本报告中，提出了一种基于光子晶体的微环谐振器（MRR）结构，该结构尺寸非常紧凑且响应速度非常快，并且已用于温度传感。本文说明了单个MRR和级联MRR的温度传感应用。通过级联两个MRR，报告的结构的灵敏度从2.9 nm /°C增加到3.4 nm /°C。材料的折射率随温度的变化而变化，这导致所提出的传感器的谐振波长发生偏移。利用时域有限差分（FDTD）仿真来查看拟议结构的透射光谱，并分析计算温度时谐振波长的偏移。拟议的设计很简单，
