Multiwavelength generation based on a mode-locked fiber laser using carbon nanotube and fiber Fabry–Perot filter

Abstract

In this paper, a novel and compact configuration of stable multiwavelength generation with a uniform wavelength interval is proposed for the first time to our knowledge. It employs a mode-locked fiber laser using a carbon nanotube and spectrum-slicing technique. A flat rectangular optical output spectrum is demonstrated by adjusting the dispersion value of the fiber-loop cavity and the pump power. With a fiber Fabry-Perot filter, 33 wavelengths with 0.2 nm spacing are obtained among the power uniformity of 2.3 dB. Moreover, the variations of output power at each wavelength are all less than 0.1 dB, which implies excellent stability of the whole structure.

“…On the other hand, multi-wavelength pulsed fiber lasers have received considerable attention for their versatile applications, including wavelength division multiplexer (WDM) fiber communication systems, photonic component characterization and optical signal processing [13][14][15][16]. Recently, Zhang et al reported a triple-wavelength passively mode-locked fiber laser in an all-normal dispersion cavity with a semiconductor saturable absorber mirror (SESAM) [17].…”
