Optical Fiber Flowmeter Based on a Michelson Interferometer [PDF]
EPJ Web of Conferences, 2023 In this work, an optical fiber flowmeter based on a Michelson interferometer is presented. The Michelson interferometer uses a long period fiber grating (LPFG) to couple light to the cladding modes followed by a section of a GO-coated single mode fiber ...

Sensing and Bio-Sensing Research, 2019 Here, we present the development of aptasensor for the label-free, stable, and sensitive detection of environmental toxin microcystin-LR (MC-LR). A thiolated aptamer used as a bio-receptor was covalently immobilized on dual-resonance long-period fiber gratings (DR-LPFG) to detect MC-LR toxin.

Optical vortex fiber laser based on modulation of transverse modes in two mode fiber
APL Photonics, 2019 Optical vortices, characterized by helical phase fronts, are usually generated outside the laser cavity using passive modulation methods. Here, we demonstrate an all-fiber laser to directly deliver mode-locked and continuous-wave vortex beams based on ...

An Ultrasensitive Long-Period Fiber Grating-Based Refractive Index Sensor with Long Wavelengths
Sensors, 2016 The response of a novel long-period fiber grating (LPFG) with a period of 180 µm to a surrounding refractive index (RI) was investigated. The results displayed that, with the increase in RI of the surrounding media of cladding glass in the grating region,
