High-Sensitivity Temperature Sensor Based on Microsphere Cavity in Super Larger Thermo-Optic Coefficient Germanium-core Fiber
A high-sensitivity temperature sensor based on an in-fiber germanium (Ge) microsphere Fabry-Perot (FP) cavity is presented. The lower melting point of the Ge core compared to that of a silica-based fiber is utilized to fabricate the microsphere at the fiber end as a FP cavity by splicing a Ge-core b...
