Abstract

A wavelength-tunable Erbium-doped fiber laser with birefringence-enhanced cavity is proposed. A 45° tiled fiber grating (45°TFG) and a section of polarization maintaining (PM) fiber are placed between two two polarization controllers (PCs). Two PCs and PM fiber are employed to enhance the birefringence effect. The 45° TFG plays the role of an in-fiber polarizer. The fiber laser is mode-locked by single walled carbon nanotube polyvinyl alcohol (SWCNTs-PVA) composite film. Central wavelength of the fiber laser can be tuned from 1552.52nm to 1575.28nm with a tuning range of 22.76nm. The demonstrated laser provided the widest tuning range in a high repetition rate all-fiber Erbium doped laser based on SWCNT.
