A switchable dual-wavelength fiber laser based on asymmetric fiber Bragg grating Fabry–Perot cavity with a SESAM

Abstract

A switchable dual-wavelength fiber laser with an asymmetric fiber Bragg grating (FBG)–Fabry–Perot (FP) cavity based a semiconductor saturable absorber mirror (SESAM) is proposed and experimentally demonstrated. The proof of concept device consists of a FGB laser with an asymmetric FBG-FP cavity, a SESAM as mode loss modulator, and a intracavity FBG as wavelength selector by changing its operation temperature. The results demonstrate the new concept of dual-wavelength fiber laser based SESAM with asymmetric FBG-FP cavity and the technical feasibility.
