Paper Abstract

This paper presents experimental results on a 70-nm-wide, quasi-continuously tunable, single-longitudinal-mode erbium-doped fiber (EDF) laser. The cavity incorporates three tunable band-pass filters; a bulk grating based tunable band-pass filter, a fiber-ring-cavity filter, and an auto-tracking saturable absorption induced grating filter generated by an un-pumped EDF. In our experiment, this laser produced a single longitudinal mode oscillation between 1510 nm and 1580 nm, an output power of 0.5 mW and a tuning step of less than 0.2 pm. Optical frequency jitter was less than 0.8 pm and the signal to source spontaneous emission ratio (S/SSE) was higher than 60 dB. A tunable single-longitudinal-mode L-band fiber laser will also be discussed in this paper.
