Programmable bandwidth-variable optical temporal differentiator based on linearly chirped fiber bragg grating and digital thermal controller
We experimentally demonstrate an all-fiber structured bandwidth variable second-order optical temporal differentiator based on linearly chirped fiber Bragg grating and digital thermal controller. The bandwidth can be ...
Directional torsion and temperature discrimination based on a multicore fiber with a helical structure
We propose and experimentally demonstrate a directional torsion sensor based on a Mach-Zehnder interferometer formed in a multicore fiber (MCF) with a ~570-μm-long helical structure (HS). The HS was fabricated into the MCF ...
Programmable Fiber-based in-band OSNR Monitoring for Flexgrid Coherent Optical Communication System
With the rapid development of ultra-dense large capacity coherent WDM optical communication networks, the monitoring of in-band optical signal-to-noise ratio (OSNR) plays an essential role to ensure signal qualities. ...
Simultaneous Measurement of Torsion and Temperature Based on Helical Structure in Multicore Fiber
An all-fiber torsion sensor based on a helical structure in a multicore fiber is demonstrated. The sensor exhibits the ability of discriminating torsion direction, torsion angle and temperature.
Highly 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 ...
