Wavelength-spacing continuously tunable multi-wavelength SOA-fiber ring laser based on Mach–Zehnder interferometer

Semiconductor optical amplifier-based multi-wavelength ring laser utilizing photonic crystal fiber

“…The PC will vary the loss slightly as seen by the lasing wavelength, hence determining whether that wavelength will be excited and it will vary the polarization state too, which will affect the efficiency of the FWM. The stability of the laser output is improved by the FWM in the PCF as described in [9,12]. The FWM phenomena makes the power distribution among different wavelengths to be a dynamic equilibrium which results in a stable laser output.…”

Investigation of Multiwavelength Laser Performance based on Temperature Variation of PMF and different SOAs

“…MWFL has been the main attractions in the application of laser source for wavelength dense multiplexing, optical sensing and many other applications. Several type of comb filters was utilized to generate the multiwavelength laser such as cascaded fiber Bragg gratings [1], Sagnac loop mirror filter [2], Fabry-Perot filter [3], Lyot filter [4][5][6], Mach Zehnder interferometer [7] and array waveguide grating [8]. Multiwavelength generation based on Lyot filter is an attractive choice for multiple lasing channels due to its advantage of low optical loss and simple design.…”

Erbium-Doped Fiber Amplification Assisted Multi-Wavelength Brillouin-Raman Fiber Laser

“…Multi-wavelength fiber laser generation from a single source has attracted many researchers in the past decades due to its potential applications in several fields [1][2][3][4]. There are several techniques applied to achieve multi-wavelength generations such as using Sagnac loop filters [5,6], array waveguide gratings [7], Mach-Zehnder interferometer [8] etc. However, due to its design simplicity and narrow linewidth output, stimulated Brillouin scattering (SBS) based multi-wavelength generations gains the most attention [9,10].…”
