Paper Abstract

In this paper, we consider a SPR sensor based on D-type optical fiber with bimetallic combination. In pursuit of both higher sensitivity and larger operating range, firstly, we separately analyze the influence of parameters such as the length of coating L, the incident angle θ and the thickness of Au-coating layer d. when the optimum parameters of sensor are determined, we analyze the performance of the sensor with different bimetallic combination consist of Au, Ag, Cu and Al. Lastly, we can get a conclusion that the sensor with L=5mm,d=25nm, θ=88° and Au-Ag at x=0.8 can provide the best performance in terms of the sensitivity and operating range.
