Abstract: With the development of optical fiber microfabrication technology, side polished fiber (SPF) has opened up a new era in fiber optic sensors. On the basis of ordinary communication fiber, the "leakage window" of the transmission light field is formed by completely or partially removing a length of fiber cladding. The light-matter interaction is used to excite, control, and detect the transmission light field in the fiber core to fabricate various sensors based on evanescent field. Optimizing the polishing parameters and guiding characteristics of the optical fiber is the key to realizing high-performance fiber optic sensors. The SPF has reliable mechanical properties, minimal insertion loss and polarization-dependent loss, making it a high-quality platform for research on the "lab on fiber". This article reviews the principle, classification, research progress, and application prospects of the SPF-based fiber optic sensors.
