“…In particular, there is active research into SWFLs that use arrayed waveguide gratings (AWGs), including a tunable fiber laser generated in the O band that was developed using semiconductor optical amplifiers (SOAs) [4], a quad wavelength fiber laser that simulta neously generates dual wavelength outputs in the O and C band regions via an SOA [5], a linear cavity dual wavelength fiber laser in the C band using EDF [6], and a high power tunable fiber laser in a C band using EDF [7]. 1 The article is published in the original.…”

This paper proposes a switchable wavelength fiber laser (SWFL) based on an arrayed waveguide grating (AWG) and a gain saturated reflective semiconductor optical amplifier (RSOA). The SWFL was experimentally implemented in the C and L bands. In order to achieve narrow linewidth oscillation, the SWFL was driven by bidirectional injection locked RSOAs. The RSOA was operated in the gain saturated region, using gain compression properties to obtain uniform power over a wide bandwidth. Based on this con figuration, we obtained 40 C band international telecommunication unit (ITU) wavelengths with 100 GHz channel spacing. The SWFL displayed a narrow 3 dB bandwidth (<0.06 nm), a high and uniform peak power (P max > 0.22 dB, ΔP max < 0.26 dB), and a high and uniform side mode suppression ratio (SMSR > 66 dB, ΔSMSR < 1 dB). The peak power and wavelength stabilities were ±0.24 dB and ±0.01 nm, respectively, at room temperature over a 1 h period.

“…Since the homogeneous gain broadening of the EDF at room temperature, it is necessary to improve the inhomogeneity and suppress the mode hopping between the adjacent modes. So many techniques have been proposed to achieve stable dual wavelength oscillations, such as incorporating a semiconductor optical amplifier in the ring cavity [4,5], utilizing nonlinear effects by using the mixed opti cal parameter oscillation [6,7] or high nonlinear pho tonic crystal fiber [8,9], passively mode locked all fiber ring dual wavelength laser [10,11], inserting a phase modulator or frequency shifter into the laser cavity [12], two tunable bandpass filters (TBFs) inside ring gain cavity [13,14], etc. The fiber Bragg gratings (FBGs) as the wavelength selective elements could significantly broaden the output wavelength range and enhance the wavelength stability [15][16][17].…”

We demonstrate a simple dual wavelength ring erbium doped fiber laser operating in single lon gitudinal mode (SLM) at room temperature. A pair of reflection type short period fiber Bragg gratings (FBGs), which have two different center wavelengths of 1545.072 and 1545.284 nm, are used as the wave length selective component of the laser. A segment of unpumped polarization maintaining erbium doped fiber (PM EDF) is acted as a narrow multiband filter. By turning the polarization controller (PC) to enhance the polarization hole burning (PHB), the single wavelength and dual wavelength laser oscillations are observed at 1545.072 and 1545.284 nm. The output power variation is less than 0.6 dB for both wavelengths over a five minute period and the optical signal to noise ratio (OSNR) is greater than 50 dB. By beating the dual wavelengths at a photodetector (PD), a microwave signal at 26.44 GHz is demonstrated.

“…Hence, several technologies of dual-wavelength fiber ring lasers have been reported, such as using a coupled-ring scheme with fiber gratings, utilizing arrayed waveguide grating (AWG), using intracavity loss optimization or Sagnac loop loss designs, employing a twin-peak reflection grating inside fiber cavity, etc. [10][11][12][13][14][15][16][17]. And then, to obtain broadband tuning range for dual-wavelength lasing, high-birefringence fiber loop mirror has also been reported [18].…”

In this investigation, we propose and demonstrate experimentally tunable and stable dual-wavelength erbium doped fiber (EDF) double-ring laser scheme using different coupling losses inside cavity loop for wavelength and mode spacing tuning. Besides, a shorter unpumped EDF is also used to filter the side-modes for lasing wavelength in singlelongitudinal-mode (SLM) operation. However, the output mode spacing of dual-wavelength could be limited owing to the homogeneous broadening nature of EDF. As a result, the output performance of the proposed fiber laser have also been analyzed and discussed, such as wavelength tuning range, output power, side-mode suppression ratio (SMSR), stabilities of lasing wavelength and power, relative intensity noise (RIN), etc. Output spectra of lasing dual-wavelength with four samples for the proposed fiber laser in the operating wavelengths under the 50% cavity loss status
