Abstract

A wavelength-encoded interferometric high-temperature sensor based on an all-solid photonic bandgap fiber (AS-PBF) is reported. It consists of a small piece of AS-PBF spliced core offset with standard single-mode fibers. Two core modes LP01 and LP11 are conveniently utilized as optical arms to form Mach– Zehnder-type interference at both the first and the second photonic bandgaps, and the maximum extinction ratio exceeds 25dB. Experimental and theoretical investigation of its response to temperature confirms that high temperatures up to 700°C can be effectively sensed using such an AS-PBF interferometer, and benefiting from a large effective thermo-optic coefficient of fiber structure, the sensitivity can be significantly enhanced (71.5pm/°C at 600°C).
