The switchable multiwavelength fiber laser (SMWLSs) using AWG and broadband FBG with tuning range 11.7nm and 0.75nm spacing are demonstrated. The switchable lasers for every channel shows flatness output power with variation 3.7dBm and peak power around −6.1dBm. The side mode suppression ratio (SMSR) of the laser is significantly improved for every channel when using broadband FBG. The improvement...
Brillouin fibre laser is demonstrated using a very short length of photonic crystal fibre (PCF). A simple ring resonator is used in the experiment which consists of a 20 m long highly nonlinear PCF and 49 cm long Bismuth-based erbium-doped fibre (Bi-EDF). The proposed Brillouin laser is able to generate up to 3 Stokes and 3 anti-Stokes lines in the 1560 nm region at a channel spacing of 0.09 nm.
