A multiwavelength laser comb using a bismuth-based erbium-doped fiber and 50 m photonic crystal fiber is demonstrated in a
ring cavity configuration. The fiber laser is solely pumped by a single 1455 nm Raman pump laser to exploit its higher power
delivery compared to that of a single-mode laser diode pump. At 264 mW Raman pump power and 1 mW Brillouin pump power, 38
output channels in the L-band have been realized with an optical signal-to-noise ratio above 15 dB and a Stokes line spacing
of 0.08 nm. The laser exhibits a tuning range of 12 nm and produces stable Stokes lines across the tuning range between Brillouin
pump wavelengths of 1603 nm and 1615 nm. 相似文献

A multiwavelength laser comb using 2.49 m Bismuth-oxide erbium-doped fiber (Bi-EDF) with different lengths of large effective
area fiber (LEAF) in a ring cavity configuration is realized. The Bi-EDF is used as the linear gain medium and LEAF is used
as the non-linear gain medium for stimulated Brillouin scattering. Out of the four different lengths, the longest length of
25 km LEAF exhibits the widest tuning range of 44 nm (1576 to 1620 nm) in the L-band at 264 mW pump power and 5 mW Brillouin
pump power. In addition, a total of 15 output channels are achieved with total average output power of −8 dBm from this laser
structure. All Brillouin Stokes signals exhibit high peak power of above −20 dBm per signal and their optical signal-to-noise
ratio of greater than 15 dB. 相似文献
