Abstract

We report the feasible design of the gas sensor based on Hollow-Core Photonic Crystal Fibers (HC-PCF) operating in the mid-IR. Hollow core photonic band gap fibres (HC-PBFs) are employed as gas cells due to their compactness, good integrability in optical systems and feasibility of long interaction lengths with gases. The challenge is in development and assembly of HC-PCF based gas cell where in alignment of two dissimilar fiber i. e. PCF and single mode fiber (SMF) with small gap of the order of 7-10 micron is reported(1). The selective absorption of laser light depicts the concentration of gas and preliminary results of Acetylene gas sensing are demonstrated.
