Abstract
We demonstrate a switchable Q-switched and mode-locked erbium-doped fiber laser (EDFL)
operating in the L-band region using the nonlinear polarization rotation effect. The switching
operation is achieved by controlling intensity-dependent loss using a polarization controller. In
Q-switching mode, the EDFL produces a pulse train with a repetition rate of 21.1 kHz, pulse width of
7.7 <i>μ</i>s, and pulse energy of 13.6 nJ. The EDFL also generates a multi-wavelength comb with a very
narrow and constant wavelength spacing of 0.045 nm and optical signal-to-noise ratio of at least 10
dB. During mode locking, the EDFL produces stretched pulses with 3-dB bandwidth of 26.2 nm, pulse
width of 350 fs, repetition rate of 2.38 MHz, and pulse energy of 48.56 pJ.
