A passively Q-switch Brillouin erbium-doped fiber laser (BEDFL) with 11 stable lasing wavelengths at peak power of -15 dBm between 1550.1 nm to 1551.0 nm, 1.67- μs pulsewidth, and repetition rate of 152.40 kHz is demonstrated. The proposed BEDFL uses a 7.7-km dispersion compensating fiber (DCF), assisted by an erbium-doped fiber amplifier (EDFA) to generate the multiwavelength output by stimulated Brillouin scattering. A graphene layer embedded in the laser cavity acts as a saturable absorber, allowing for Q-switched pulses.
