Description/Abstract

Single frequency Er3+-doped fibre lasers are emerging as interesting alternatives to distributed feedback (DFB) diode lasers for use in future high-capacity 1.5µm WDM communication systems, as well as CATV, LIDAR, fibre-optic sensor and spectroscopy applications. In general, fibre lasers are fibre-compatible, scalable to high output powers and have low intensity noise and kHz linewidths. Most work on single-frequency fibre lasers has been concentrated on: 1) long travelling-wave fibre ring-lasers, where single-mode operation is obtained by eliminating spatial hole-burning (the factor which causes multi-mode operation in fibre lasers), and 2) short linear-cavity distributed Bragg reflector (DBR) fibre lasers employing fibre grating Bragg reflectors for feedback and mode suppression. Recently also a fibre distributed feedback (DFB) laser, where the feedback is provided by one single fibre grating occupying the entire cavity length and a single-frequency fibre Fabry-Perot micro laser have been demonstrated.
