Tunable mode locked Erbium-doped fiber laser based a tilted fiber grating and carbon nanotube saturable absorber

Abstract

We demonstrate a continuous tunable mode locked Erbium fiber laser using a tilted fiber grating based birefringent filter and carbon nanotube based saturable absorber. The central wavelength can be tuned from 1558 nm to 1564 nm while maintaining ultrashort pulse emission.
