Hollow Optical Fiber Surface Plasmon Resonance Sensor Based on Light Intensity Detection
A hollow optical fiber surface plasmon resonance (SPR) sensor based on light intensity detection is proposed. The 532 nm laser is used as the light source, and the performance of the sensor is investigated. The performance of the sensor is theoretically analyzed based on the light transmission model. Experimental results are in agreement with theoretical results. The highest sensitivity of 8380.3 μW/RIU and the optimum resolution of 5.5×10-6 RIU can be obtained by the sensor in linear region. The resolution of the proposed sensor is improved by two orders of magnitude compared to that of the hollow optical fiber SPR sensor based on wavelength detection. The experimental system is simple, and it is beneficial to miniaturization of devices.
