Abstract

Typical DBR (distributed Bragg reflector) fiber laser consists of a piece of an amplifying fiber terminated by two fiber Bragg gratings (FBGs) serving as resonant mirrors. For single longitudinal-mode lasing the length of an amplifying fiber should be determined correctly via numerical modelling. In...
