Triple-wavelength fiber ring laser based on a hybrid gain medium actively mode-locked at 10 GHz.
In: CNSDSP 2008 - 6th International Symposium on Communication Systems, Networks and Digital Signal Processing, 25-25 July 2008 , Graz, Austria.
A fiber ring laser based on a hybrid gain medium that produces three simultaneously mode-locked wavelength channels is presented. The lithium niobate based modulator used to actively mode-lock the laser cavity at 10 GHz is birefringence compensated to reduce its polarization sensitivity. A Lyot filter defines the lasers multiwavelength spectrum which has a wavelength spacing of 1 nm. The polarization sensitive nature of the laser cavity and its affect on the performance of the laser is discussed.
