Abstract

Sensor related properties of a small core (4.1μm) Ge-doped photonic crystal fiber (PCF) are being reported. Fiber Bragg gratings with 35% and almost 100 % reflectivity were written in the Ge-doped PCF before and after hydrogen loading, respectively, by use of a UV laser. A 5.6pm/°C temperature sensitivity of the FBG was observed. Additionally, a novel method is demonstrated to splice such PCF by use of a commercial fusion splicer with default splice parameters for standard single mode fibers (SMF). No parameter adjustments are required to splice the PCF to various SMFs and a low splice loss of 1.0 ~ 1.4dB can be achieved. No splice interface emerges at the splice joint, which is of advantage for the sensing applications of such a PCF.
