A polarization-maintained coupled optoelectronic oscillator(COEO) with its performance significantly improved by a short-length unpumped erbium-doped fiber(EDF) is reported and experimentally investigated.A 10 GHz...
Switchable single and double Brillouin multiwavelength and pulsed laser is successfully demonstrated. Brillouin spacing can be switched from single(0.08 nm) to double spacing(0.16 nm) or vice versa by swapping the...
We demonstrate a femtosecond mode-locked erbium-doped fiber laser(EDFL) using a nickel oxide(Ni O) as a saturable absorber(SA). Ni O nanoparticles are hosted into polyethylene oxide film and attached to fiber fe...

We demonstrate a switchable Q-switched and mode-locked erbium-doped fiber laser (EDFL) operating in the L-band region using the nonlinear polarization rotation effect. The switching operation is achieved by controll...
We describe and compare the performances of two crucial configurations for a tunable dual-wavelength fiber laser, namely, the linear and ring configurations. The performances of these two cavities and the tunability i...
We demonstrate a multi-wavelength erbium-doped fiber laser (EDFL) using erbium gain and four-wave mixing (FWM) effect in a piece of erbium-doped fiber (EDF) with high erbium ion concentration. The EDF has a pump...
