Photonic Crystal Fiber Mach-Zehnder Interferometer for Refractive Index Sensing
We report on a refractive index sensor using a photonic crystal fiber (PCF) interferometer which was realized by fusion splicing a short section of PCF (Blaze Photonics, LMA-10) between two standard single mode fibers. The fully collapsed air holes of the PCF at the spice regions allow the coupling of PCF core and cladding modes that makes a Mach-Zehnder interferometer. The transmission spectru...
متن کاملRefractive index sensor using microfiber-based Mach-Zehnder interferometer.
A simple and robust refractive index (RI) sensor based on a Mach-Zehnder interferometer has been demonstrated. A section of optical microfiber drawn from silica fiber is employed as the sensing arm. Because of the evanescent field, a slight change of the ambient RI will lead to the variation of the microfiber propagation constant, which will further change the optical length. In order to compen...
متن کاملMach-Zehnder Interferometer Refractive Index Sensor Based on a Plasmonic Channel Waveguide
A Mach-Zehnder interferometer based on a plasmonic channel waveguide is proposed for refractive index sensing. The structure, with a small physical footprint of 20 × 120 μm², achieved a high figure of merit of 294. The cut-off frequency behaviour in the plasmonic channel waveguide resulted in a flat dispersion curve, which induces a 1.8 times larger change of the propagation constant for the gi...
متن کاملNovel Fiber Optic Sensor Based on In-line Core-cladding Intermodal Interferometer and Photonic Crystal Fiber
− 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 t...
متن کاملHighly sensitive strain sensor based on helical structure combined with Mach-Zehnder interferometer in multicore fiber
Optical fiber sensors for strain measurement have been playing important roles in structural health monitoring for buildings, tunnels, pipelines, aircrafts, and so on. A highly sensitive strain sensor based on helical structures (HSs) assisted Mach-Zehnder interference in an all-solid heterogeneous multicore fiber (MCF) is proposed and experimentally demonstrated. Due to the HSs, a maximum stra...
