Abstract: Fiber-based surface plasmon resonance (SPR) sensor is the extension and development of the traditional prism-based SPR sensor. Two bottlenecks limit the application of fiber-based SPR sensors:the testing sensitivity is relative low and it is difficult to perform the multichannel sensing detection. In recent years, we explore a SPR sensing technology based on the micro-structured fiber, and construct various micro-structured fiber-based SPR sensors, which break through the current two problems:improving the detecting sensitivity and performing the multi-channel measurement of biochemical sensing. The utilization of microstructure fibers for SPR sensors contributes to reducing the size of the sensing system greatly, ensuring the convenience of integrating with the optical fiber system. In summary, the microstructure fiber-based SPR sensors have a broad application prospects.
