Temperature effect on the performance of a 1D grating-based surface-plasmon resonance sensors

We have theoretically studied the influence of temperature on the performance of a 1D grating sensor based on surface plasmon resonance. Rigorous coupled wave analysis method has been utilized to study the effect of the temperature on the sensing performance. The performance of the sensor has been evaluated on the basis of detection accuracy (DA), the sensitivity (S) and the quality parameter (). The effect of temperature on the DA, and S of the sensor with two different metals (gold and silver) has been compared. Our analysis exhibits that increasing of temperature may lead to poor detection accuracy and quality of the sensor, but the sensitivity is very stable with the change of temperature. Further, the results confirm that the room temperature T=300K provides a high DA and a high S, and a good quality.
