Paper Abstract

In this paper, we propose and demonstrate a novel room temperature multiwavelength erbium-doped fiber laser (EDFL) scheme with the wavelength spacing less than homogeneous broadening linewidth based on the inter-channel four-wave mixing (FWM). A stable CW MW-EDFL is firstly implemented based on a length of high nonlinear photonic crystal fiber (HNL-PCF) and sampled-fiber Bragg grating (SFBG). We further extend the idea of FWM induced self-stable operation of MW-EDFL to the multiwavelength mode-locking fiber ring laser to generate ultra-short, ultra-fast, multiwavelength and synchronized pulse sources. 2 and 4 wavelengths anchored on ITU-T standards with 100 GHz channel spacing are successfully mode-locked at 10-GHz simultaneously, without gain competition.
