“…Moreover, EDF lasers have also provided the characteristics of widely tunable range, narrow linewidth, SLM oscillation, and high output power [6]. Unfortunately, due to the homogeneous broadening, gain completion and mode-hopping of EDF, EDF lasers have usually led to unstable multilongitudinal-mode (MLM) initiation [7]. Thus, to overcome and suppress the challenges of MLM noise, the approaches of utilizing the variable fiber Bragg grating Fabry-Perot etalon [4], a multiple-ring cavity [8,9], EDF based saturable absorber (SA) [10,11], Sagnac-ring design [12] and tunable reflection interferometer [13] have been reported and studied.…”

In the paper, we report and exhibit a C-band erbium-doped fiber (EDF) based gain medium laser together with a 5 m unpumped EDF saturable absorber (SA) to attain broadly wavelength-selectable range and single-longitudinal-mode operation. Here, the whole tunability range of 1521.0 to 1601.0 nm (C plus L bands) can be accomplished by the designed EDF laser scheme. The output power and optical signal-to-noise ratio of the EDF laser are detected between −10.9 and 2.3 dBm and 33.1 and 45.1 dB/0.06 nm, respectively. In addition, the achievable SLM operation range runs from 1521.0 to 1581.0 nm due to the absorption limit of the EDF SA. The detected output stability and Lorentzian linewidth are also experimentally considered and significantly discussed.

“…The SBS is selected as the gain mechanism because of its relatively low nonlinear threshold, offers great stability as a signal generator, and narrow linewidth [7]. A straightforward method to generate microwave signals is by using optical heterodyne detection with either two independent lasers with required wavelength spacing or dual-wavelength based laser [8]. Generating signals above 11 GHz requires multiwavelength laser generation, whereas only two lasing lines will be selected for the heterodyning process at the photodiode [9].…”

An all-optical microwave signal generator based on multiwavelength Brillouin-Erbium fiber laser (MBEFL) is proposed. The MBEFL unit is designed at fixed wavelength spacing of 0.084 nm, which corresponds to ~10 GHz carrier signal. The underlying mechanism MBEFL unit is by recycling the backscattered Stokes waves into the cavity to generate higher-order Stokes waves. Heterodyning process is then applied to the Brillouin pump (BP) consisted of first-order Brillouin Stokes (BS1) (0.084 nm spacing) and second-order Brillouin Stokes (BS2) (0.168 nm spacing) signals by using a photodetector (PD). The heterodyned outputs are microwave signals at the frequencies of 10.56 GHz and 21.2 GHz, relative to first order and second order Stokes waves, respectively. These microwave signals are experimentally achieved by controlling the EDF pump power where the EDF pump power can be as low as 20 mW.

“…Stable and tunable erbium-doped fiber (EDF) ring lasers are now promising candidates for several photonics applications, such as optical wavelength division multiplexing (WDM) transmission, optical fiber sensing, light detection and ranging (LIDAR), microwave and millimeter-wave photonics, and optical instrument measurement [1][2][3][4][5]. EDFs could be utilized extensively to act as the gain medium in fiber-based laser architecture [6,7].…”

Use of proper cavity loss for a stable single-longitudinal-mode erbium fiber laser

et al. 2017

View full text Add to dashboard Cite

A stable and selectable erbium-doped fiber (EDF) ring laser configuration with single-longitudinal-mode (SLM) output is proposed and demonstrated in this paper. In the proposed laser scheme, a proper cavity loss is utilized for significant suppression of the side mode. In the experiment, the different coupling ratios required to produce various cavity losses in the proposed fiber laser are analyzed. Here, to reach the wavelength selection, several fiber Bragg gratings (FBGs) and an optical tunable bandpass filter (OTBF) in the C-band range are employed for demonstration. In addition, the output performance with respect to stability and SLM in the proposed EDF ring laser are also investigated simultaneously.
