We purpose a new design configuration of a phase modulated mode-locked figure eight laser(F8L)with two EDFAs and experimentally measure its characteristics in this paper. Our designed F8L mode-locked laser concludes two EFDAs, an isolator, a phase modulator(PM), two polarization controllers(PC)and two unbalance couplers(90:10). Two
PCs are put at the input and output of two EDFAs to fix the polarization of light to generate a stable mode-locking laser
output. A nonlinear loop mirror(NLM) is used to make the pulse being compressed. The PM can add an RF modulation signal to help mode-locking of the ultrashort pulse. Preliminary experimental demonstration is given in this paper. We present the time relative responses of this system for high speed photography triggering.
In this paper, we propose a new design configuration of a novel multiple outputs and multiple wavelength fiber ring-optical lasers and experimentally measure its characteristics. This novel laser has output wavelength bands in 1310 nm and 1550 nm windows, respectively, at each output port of the fourteen outputs. The CNR, CSO, CTB are calculated and compared for the fourteen outputs. Such a multiple-output and multi-wavelength (MOMW) fiber ring laser can be applied in WDM/SDM/SCM fiber networks.
