Based on the dual-resonance principle around the dispersion turning point, a scheme of chiral long-period fiber gratings (CLPGs) formed by twisting a high-birefringence (Hi-Bi) fiber is herein proposed to realise ultra-broadband flat-top circular pol

Herein, we propose a structure to simultaneously compress the distributed feedback (DFB) laser array’s linewidth. The proposed structure is meticulously designed to ensure single longitudinal mode operation via the interference phenomenon between t

A tri-component (3-C) fiber-optic interferometric accelerometer using weak fiber Bragg grating array is proposed and tested. Experimental results showed that the axis sensitivity was about 55 dB and the suppression effect of cross-axil sensitivity is

A novel, to the best of our knowledge, mid-infrared chalcogenide (ChG) on magnesium fluoride ( M g F 2 ) waveguide gas sensor was fabricated by using the lift-off method. M g F 2 was used as a lower cladding layer to increase the external confinement

We aim to develop a nonintrusive, reliable, convenient flow rate measurement and leak detection method. The flow rate is known to be related to the vibration excited by the turbulent internal flow, but there exists some scatter in the vibration data

The reported chalcogenide (ChG) rectangular waveguide sensors with a small evanescent field need a large waveguide length to obtain an enhanced light-gas interaction effect. To make such sensors compact and improve the light-gas interaction effect, a
