“…Room temperature multiwavelength operation in a single EDF laser was demonstrated by adding a frequency shifter into the ring cavity to prevent steady-state laser operation and single-frequency oscillation 5 . In a hybrid Brillouin/erbium fiber laser, multiwavelength operation has also been obtained 6 . Other methods, like optical feedback, polarisation hole burning and nonlinear gain in optical fiber have also been investigated 7,8 .…”

We propose a simple Er-doped fiber laser configuration for achieving stable dual-wavelength oscillation at room temperature, in which a high birefringence fiber Bragg grating was used as the wavelength-selective component. Stable dual-wavelength oscillation at room temperature with a wavelength spacing of 0.23nm and mutually orthogonal polarisation states was achieved by utilising the polarisation hole burning effect. An amplitude variation of less than 0.7dB over 80s period was obtained for both wavelengths.

“…In order to increase gain and number of Brillouin Stokes lines, it is customary to use a hybridgain configuration. This idea is evident in multiple wavelength Brillouin erbium fiber lasers (MBEFLs) [8,9]. In addition, a Bi-EDF with larger emission cross section and broader emission bandwidth is usually used to generate Bi-EDFA having wider operational wavelength region extended especially in the L band region (1565-1625 nm) [10,11].…”

Abstract.A multiple wavelength laser source is generated by a Brillouin seed signal and a compacted hybrid Raman / bismuth-based erbium doped fiber amplifier (Bi-EDFA) in a linear cavity. The gain media of the Raman/Bi-EDFA is only a 2.15 m Bi-EDF pumped bi-directionally by two laser diodes (LDs). In comparison to all of the conventional multiple wavelength sources generated via using the same Bi-EDF and LDs, the proposed multiple wavelength source has much more number of lines due to using Raman and EDF amplification.

“…For Dense Wavelength Division Multiplexing DWDM applications, multiwavelength Brillouin Erbium fiber laser was realized where each Stokes signal acts as a new pump to generate another Stokes signal downshifted by 11 GHz (about 0.088 nm). 24 CW channels around 1560 nm are obtained by this technique [8][9][10].…”

Abstract-A multimode Brillouin Erbium Fiber Laser BEFL, at 1550 nm band, with in-cavity intensity modulation is demonstrated. The output of the laser is in the form of nanosecond pulses. The longitudinal mode separation is increased, which results in both reducing the number of oscillation modes and, at the same time, changing the output pulses repetition rate to be multiples of the round trip cavity frequency. It is also demonstrated that the number of modes is greatly reduced by the combination of active mode locking and the group velocity dispersion arising from the change in the refractive index at each mode due to the change in its gain within the Brillouin gain bandwidth. A case of a quasi single mode is reached where the output is nearly CW with very low sinusoidal modulation index.
