Investigation of passively mode-locked erbium doped fiber ring laser due to nonlinear polarization rotation

Abstract

Passively mode-locked erbium doped fiber ring laser was investigated. We present optimization of laser configuration where nonlinear polarization rotation was used for modes synchronization. Simulations of pulse propagation inside a laser cavity were applied in order to confirm the optimisation technique. Experimental results are presented and more than 32-nm spectral width of the output frequency comb was obtained. © 2008 Association of Polish Electrical Engineers.
