- Abstract:
- 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.
