Abstract
We demonstrate a multiple wavelength Brillouin/erbium fiber laser in a linear
cavity configuration. The laser cavity is made up of a fiber loop mirror on one end
of the resonator and a virtual mirror generated from the distributed stimulated
Brillouin scattering effect on the other end. Due to the weak reflectivity provided
by the virtual mirror, self-lasing cavity modes are completely suppressed from the
laser cavity. At Brillouin pump and 1480-nm pump powers of 2 and 130 mW,
respectively, 11 channels of the demonstrated laser with an average total power of
7.13 dBm can freely be tuned over a span of 37-nm wavelength from 1530 to 1567 nm.
