Tunable Multiwavelength Brillouin Erdoped Fiber Laser with 0.173 nm Spacing
A tunable multiwavelength brillouin/erbium fiber laser with doubleBrillouinfrequency spacing based on a fourport circulator was experimentally demonstrated. The fiber laser configuration formed by fourport circulator isolates the oddorder brillouin stokes signal to circulate within the cavity only. In addition, it also allows propagation of the incoming brillouin pump and evenorder Stokes signals from fourport circulator to output coupler. A fiber FabryPerot tunable filter was used to manipulate the location of selflasing cavity and to increase power for multiwavelength oscillation. It can be obtained that a wideband tuning range and more output channels. At the brillouin pump power of 8 dBm and the 980 nm pump power of 279 mW, 6 output channels with 0.173 nm spacing and tuning range of 28 nm from 1535 nm to 1563 nm were achieved.
