Novel Fiber Optic Sensor Based on In-line Core-cladding Intermodal Interferometer and Photonic Crystal Fiber
نویسندگان
چکیده
− We propose a simple all-fiber structure based on intermodal interference between a core and a cladding mode of an endlessly single-mode photonic crystal fiber section sandwiched between a lead-in and lead-out SMF-28 fiber. The sensitivities to strain, pressure and temperature are measured. The interferometer is compared to an interferometer based on LP01-LP02 SMF-28 fiber and to a PCF-based tapered LPG.

متن کاملGas Sensor Based on Large Hollow-Core Photonic Bandgap Fiber
One concern in using photonic band-gap fiber (PBGF) as a gas sensor is the response time. In this type of the gas sensors, response time is the time required for gas to diffuse into the hollow-core. So considering a large hollow-core PBGF (HC-PBGF), the response time can be significantly reduced. But in the large HC-PBGF, the fundamental issue is the presence of higher order modes (HOMs). Somet...
