“…MWFL systems have been demonstrated using photonic crystal fibres (PCFs) [1], Sagnac loop mirrors (SLMs) [2] and high birefringence (Hi-Bi) fibers [3,4] as well as utilizing non-linear effects such as stimulated Brillouin scattering (SBS) [5][6][7]. Fibre Bragg gratings (FBGs) used as a reflector in a cascade configuration [8] or FBGs written on birefringence fibres [9] for compactness have also become popular choices for generating multiwavelength outputs. When the generated multiwavelength output is routed through a wavelength selective filtering mechanism such as the SLM [4], the SWFL can now easily switch between discrete wavelengths, thus reducing the need for tedious tuning procedures while at the same time providing a robust selectable wavelength laser source that can be deployed in the field.…”

A compact switchable multiwavelength fibre laser (SWFL) is proposed and demonstrated using a bismuth based erbium doped fibre amplifier (Bi-EDFA) and a Sagnac loop mirror (SLM) in a ring cavity. The proposed compact SWFL can generate up to 6 switchable wavelengths with an average peak power of 11 dBm and also shows good stability over time with a high side mode signal ratio (SMSR) of 40 dB that negates minor fluctuations in the laser output. The Bi-EDF based gain medium gives the SWFL a large usable bandwidth of up to 80 nm, and it is expected that this will allow the SWFL to be used as a tunable laser source for high power applications to meet increasing demand.

“…A FLM of one-stage high birefringence (HiBi) fiber and polarization controller (PC) is a simple filter device, in which the filter spectrum depends on the PC and Hi-Bi fiber. However, the wavelength interval is only depends on the PMF [6]. The only way of varying the filter interval is to use different Hi-Bi fiber length in the FLM; it is not practical in real optical systems.…”

Abstract-A fiber loop mirror (FLM) with two-stage high birefringence (Hi-Bi) fibers is theoretically and experimentally studied for various rotation angles and Hi-Bi fiber lengths. The experimental spectra are observed to be in good agreement with the theoretical spectra, verifying our theoretical model. The wavelength interval of the comb filter depends on the Hi-Bi fiber lengths and rotation angles. By varying the rotation angle from 0 • to 90 • , a comb-like transmission spectrum with small wavelength spacing is evolving into an exotic but periodic transmission spectrum and eventually become a larger wavelength spacing transmission spectrum. The FLM is useful in many applications such wavelength division multiplexing power equalization and management, switchable multi-wavelength fiber laser, optical switch and etc.

“…Furthermore, the homogenous broadening mechanism also leads to mode competition and subsequently fluctuating and unstable laser powers [1]. Overcoming this limitation required complex and expensive methods such as cooling the EDF with liquid nitrogen [2] or using specially designed twin-core EDFs [3], which is not practical in real world applications. As a result, other means of overcoming the limitations posed by the homogenous broadening mechanism in the EDF had to be found.…”

Abstract-We propose and demonstrate a Multiwavelength Brillouin Bismuth/Erbium Fibre Laser (MBBEFL) with the ability to control the number of wavelength channels generated. A multi-wavelength comb output is obtained using a 7.7 km DCF as a non linear gain medium to generate Stokes wavelengths through the process of Stimulated Brillouin Scattering (SBS). The DCF is pumped by a Raman pump source at 400 mW to lower the dispersion loss and promote the generation of the Stokes wavelengths. A 49 cm long Bismuth based Erbium Doped Fibre (Bi-EDF) is used as an optical amplifier to provide the necessary gain for the Brillouin Pump and also act as the gain medium for the generated Stokes signal.
