| Abstract | ||
| In this study, high input pump power Raman pump (RP) based multiwavelength Brillouin fiber laser with single Brillouin spacing lines were demonstrated at the room temperature. A simple ring cavity with a highly nonlinear fiber was used as the Brillouin gain medium (BGM) and a 3-dB coupler was employed for distinction of a single spacing (odd-ordered) Brillouin frequency shift Stokes signal. The results indicate that at Brillouin pump (BP) power of 8 dBm and RP power of 900 mW, 130 lines of single spacing comb lines were produced with a channel wavelength spacing of 0.0782 nm, at the BGM length of 2km. Moreover, the number of lines reduced as the RP power and the BGM length were reduced. It is also revealed that the BFL can be widely tuned in C and L-band range within wavelength region from 1550nm to 1620nm. | ||
