Abstract
This paper presents chemical vapor sensing properties of twin-core photonic crystal fiber-based in-reflection interferometer. 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. As an example we demonstrate acetone vapor detection and discuss the potential applications of the proposed device.
