Pump-noise-induced linewidth contributions in distributed feedback fiber lasers

Pump-noise-induced linewidth contributions in distributed feedback fiber lasers
Pump-noise-induced linewidth contributions in distributed feedback fiber lasers
We investigate experimentally and theoretically the linewidth of a Er-Yb doped DFB fiber laser. We find that two noise sources are mainly responsible for the observed behavior, fundamental thermal noise at low pump power levels and temperature fluctuations induced by pump intensity noise at higher powers. Potential techniques to overcome these limitations are discussed.

Abstract

We investigate experimentally and theoretically the linewidth of a Er-Yb doped DFB fiber laser. We find that two noise sources are mainly responsible for the observed behavior, fundamental thermal noise at low pump power levels and temperature fluctuations induced by pump intensity noise at higher powers. Potential techniques to overcome these limitations are discussed.
