Optical fibers have been widely applied to telecommunication,imaging,lasers,and sensing.Among the different types of fibers,photonic crystal fibers[PCFs],also called microstructured optical fibers,characterized by air holes arranged along the length of fibers have experienced tremendous advance due to their unique advantages.They are regarded as a desirable platform to excite surface plasmon resonance[SPR]because of easy realization of phase matching conditions between the fundamental core mode and the plasmonic mode,which plays a critical role in miniaturization and integration of SPR sen-sors.In this mini-review,the current status of PCF sensors based on SPR is summarized.The theory of SPR is discussed,and simulation methods for PCF-SPR sensors are described.The important parameters including the refractive index detection range,resonance wavelength,and spectral sensitivity responsible for the sensing properties of PCF-SPR sensors are reviewed.The fabrication and the comparison of performances are also illustrated,and,finally,the challenges and future perspectives are outlined.
