Abstract
In an effort to realize a compact and integrated ultrafast fiber laser system, we propose a fiber component serving as a wavelength division multiplexer (WDM), output coupler (OC), and mode-locker by a magnetron-sputtering saturable absorber (SA) on a laboratory-tapered coupler. With the function-integrated coupler, an Er-doped mode-locked fiber laser with 112 MHz repetition rate, 286 fs pulse width, and 87 dB signal-to-noise ratio (SNR) is demonstrated. The noise feature of the mode-locked laser is also characterized. To the best of our knowledge, this is the first demonstration of a mode-locked fiber laser based on a WDM/OC/SA integrated device.
