Widely Tunable C + L Bands Multiwavelength BEFL With Double-Brillouin Frequency Shifts

A wideband multiwavelength Brillouin-erbium fiber laser (BEFL) with double Brillouin frequency spacing is demonstrated. The fiber laser structure utilizes a tunable band-pass filter and a pre-amplified Brillouin pump technique within a ring cavity. An average of six Brillouin-Stokes signals in C + L...

More Information
Summary:A wideband multiwavelength Brillouin-erbium fiber laser (BEFL) with double Brillouin frequency spacing is demonstrated. The fiber laser structure utilizes a tunable band-pass filter and a pre-amplified Brillouin pump technique within a ring cavity. An average of six Brillouin-Stokes signals in C + L bands with a constant wavelength spacing of 0.174 nm can be turned over a span of 80 nm from 1530 nm to 1610 nm. Total average output power of 8.5 mW from this laser structure was achieved. All the generated Brillouin-Stokes signals exhibit good stability, and high peak power of above - 10 dBm per signal was demonstrated.
