A new type of tunable broadband fiber-optic acousto-optic sensor was experimentally demonstrated by utilizing a bubble-on-fiber (BoF) interferometer. A single micro-bubble was generated by injecting a heating laser at λ = 980 nm on the metalized fac

Optical orthogonal frequency-division multiplexing (OOFDM) signal is sensitive to nonlinear distortions induced by optical modulators. We propose and experimentally demonstrate a digital pre-distortion (DPD) algorithm to linearize the optical modulat

A Mach-Zehnder interferometer (MZI) composed by a pair of long period gratings (LPGs) fabricated in silica microfiber for sensing applications is demonstrated. Each LPG is fabricated with a pulsed CO2 laser by creating six periodical deformations alo

The relation of beat frequency, sweep rate, optical frequency modulation excursion and length of fiber under test (FUT) based on tunable semiconductor laser is studied. Experimental results show that the frequency of beat signal will increase when th

In this paper, we propose and demonstrate a technique to realize multiwavelength operation in erbium-doped fiber lasers (EDFLs) by inserting two Fabry Pérot laser diodes (FP-LDs) in the laser cavity respectively in cascaded and parallel way. The FP-

We report the fabrication, characterization and application of extremely short linear-cavity distributed Bragg reflector fibre lasers (DBR-FLs) written in commercial erbium-doped fibres. The DBR-FL has a total length of 7 mm, of which the nominal cav

A tunable broadband fiber-optic acoustic sensor was demonstrated by utilizing a bubble-on-fiber (BoF) interferometer. Single micro-bubble was photothermally generated by injecting a heating laser at λ= 980 nm on the metalized facet of an optical fib
