Flat output and switchable fiber laser using AWG and broadband FBG

Abstract: 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 is about 27.7dBm. The laser for every channel also shows the good stability within the 2h operation. [Copyright &y& Elsevier]
