Abstract
We demonstrate a triple Brillouin frequency spacing, multi-wavelength Brillouin laser combined with two cavities: a single Brillouin frequency spacing cavity and a double Brillouin frequency spacing cavity. In this simple structure, the optimization of multi-wavelength lasing is done with proper adjustments of Brillouin pump (BP) power and 980-nm pump power. When setting the BP power to 3-dBm and 980-nm pump power to 27.78 dBm, up to ten channels with frequency spacing of 0.26 nm are generated. The output wavelength can be tuned in a wide range of 45 nm, from 1525 to 1570 nm. We also compared and analyzed this scheme under the condition of single linear cavity 1 and double ring cavity 2. The proposed multi-wavelength laser has the potential applications in the areas of space optical communication and optical communications and microwave signal source.
