Abstract
We report and demonstrate a twin-core photonic crystal fiber based in-reflection interferometer for chemical vapor detection. The interferometer is composed of end-cleaved twin-core photonic crystal fiber (TC-PCF) and fiber circulator. Infiltrating chemical molecules in the air holes of TC-PCF lead to change in inter-core effective index difference and associated fringe shift in the interferometer. The potential applications of the proposed device are also discussed.
