Generation of a multi-wavelength Brillouin erbium fiber laser with low threshold in multiple frequency spacing configurations

Spectral optimization of Stokes channels for multi-wavelength Brillouin fiber lasers

“…This behavior is a characteristic signature of EDFA saturation, in which the power increases to the maximum possible value before complete EDFA saturation. It is very important to emphasize that employing the same setup displayed in figure 1, without performing an adequate optimization of the laser parameters, a total of 15 Stokes channels, excluding the Brillouin pump, were experimentally generated in our previous work within a 30 dB range down from the peak [20]. This demonstrates the effectiveness of optimizing the parameters investigated here, allowing not only to increase five times (from 15 to 75) the number of Stokes channels with the same experimental setup but also to generate them with a significantly better flatness.…”

“…low intracavitary losses, mechanical robustness, and compact structures. Some multi-wavelength fiber laser architectures can be built by employing fiber Bragg gratings [12], Mach-Zehnder interferometers [13], Sagnac fiber loop filters [14], Lyot filters [15], Fabry-Perot filters [16], nonlinear optical loop mirrors [17], and also very often nonlinear effects such as nonlinear polarization rotation effect [18], four-wave mixing [19], and stimulated Brillouin scattering (SBS) [20].…”

Molten fluoride salt-assisted synthesis of titanium carbide (Ti2C) MXene and its application for 2 µm mode-locking in a thulium-doped fiber laser

“…Since the advent of optical fibers, there has been a parallel but equally important effort on the development of optical range of these optical amplifiers and lasers to cover the S-, C-, and L-bands simultaneously [11][12][13]. There is also interest in generating dual-wavelength and multiwavelength outputs based on the Brillouin effect, arrayed waveguide gratings, and countless other methods [14][15][16][17][18][19][20][21][22]. The development of optical fiber-based devices has come a long way, with ever-expanding interest in sensing [23][24][25][26][27].…”

kHz pulse generation with Brillouin erbium fiber laser

“…So far, various BEFLs have been reported based on self-starting [1,7], Raman [8] or Rayleigh assisted [9] configurations. These lasers show very similar spectral characteristics and have been suggested to be useful for optical communication [10,11], in particular for wavelength division multiplexer (WDM) systems. However, these lasers have not been studied for pulse generation despite numerous demonstrations of different configurations of BEFLs.…”
