“…These findings proved that the fluctuation experienced by the multiwavelength spectrum over 120 min is low thus, the output spectrum is stable. A stable output spectrum has benefitted greatly in the telecommunication industry as long-distance communication over 100 km now experiences very low signal power variation [4].…”

“…The main attraction of MWFL is its configuration of a simple and compact setup [2]. Multiwavelength random fiber laser (MWRFL) was proposed and implemented using photons that are distributed randomly inside a fiber cable and feedback in the form of Rayleigh backscattering (RBS) signals are amplified for laser production [3,4]. The unique advantage of RBS signals produced inside an MWRFL system is that the signal oscillates consistently, even at higher amplification [5].…”

Effect of Rayleigh backscattering on the multiwavelength random fiber laser bandwidth

We investigated the effect of Rayleigh backscattering on the bandwidth of a multiwavelength random fiber laser (MWRFL). This MWRFL is based on an erbium-doped fiber amplifier (EDFA) as the gain medium and a Lyot filter as the wavelength-selective device. A high number and stable lasing line is generated with the assistance of a nonlinear polarization rotation effect induced by highly nonlinear fiber (HNLF) and optimized by a polarization controller. Longer single-mode fiber (SMF) produces wider multiwavelength bandwidth as compared to shorter SMF lengths, as 10 km, 3 km, and 0.1 km obtained 6.24 nm, 5.76 nm, and 2.75 nm wavelength bandwidth, respectively. When the SMF is removed from the setup, no Rayleigh backscattering is provided in the cavity, which led to a narrower multiwavelength bandwidth of 2.69 nm. Subsequently, the alteration of EDFA power, half-wave plate (HWP) angle, and quarter-wave plate (QWP) angles affected the degradation of multiwavelength performance. The best output spectrum is achieved at an EDFA power of 18 dBm, a HWP angle of 60°, and a QWP angle of 105°. The laser stability over a period of 120 minutes was excellent with a peak power deviation of 1.33 dB.
