Brillouin-Raman fiber laser with switchable wavelength spacing based on Brillouin pump distribution
A switchable multi-wavelength Brillouin-Raman fiber laser (MW-BRFL) is presented in this work. The MW-BRFL consists of a full-open linear cavity in which dispersion compensating fiber is employed as the gain medium for Brillouin and Raman amplification. The switching operation for single- and do...

| description | A switchable multi-wavelength Brillouin-Raman fiber laser (MW-BRFL) is presented in this work. The MW-BRFL
consists of a full-open linear cavity in which dispersion compensating fiber is employed as the gain medium for
Brillouin and Raman amplification. The switching operation for single- and double-wavelength spacing MW�BRFL can be implemented by controlling Brillouin pump (BP) power distribution and direction that enters the
laser cavity via two fiber-entry points. This is achievable by optimizing the splitting ratio of an optical coupler
and the initial BP power. For the proposed laser setup, a 30/70 optical coupler was found to be the optimum. By
setting the initial BP power at − 3.0 dBm, 246 laser lines with 20-GHz frequency spacing were observed. The
transformation to 10-GHz frequency spacing was attained by increasing the BP power to 11.8 dBm that resulted
in 483 laser lines. All the counted laser lines had 3 dB peak power variation and were spread across a 38 nm
bandwidth. In a nutshell, the proposed MW-BRFL is promising with respect to its performance, simplicity and
flexibility. |
