Abstract

A tapered-microfiber sensor near the dispersion turning point (DTP) is theoretically researched and experimentally fabricated by carefully tapering a standard single mode fiber (SMF). With respect to other tapered fiber sensors, the microfiber sensor near DTP has quite high sensitivity, which is verified by the theoretical analysis in this work. The influences of two critical structural parameters, the tapering length and the waist diameter, on the occurrence of DTP are also studied. Furthermore, the preparation technology of this sensor is experimentally explored. As last, the transmission spectrum of the fabricated microfiber DTP sensor is highly consistent with that in theoretical calculation. These results show its potential for humidity sensing and other environmental trace detection.
