摘要
A semi conductor-optical-amplifier-based fiber laser incorporating with a phase-shifted phase-only sampled fiber Bragg grating (FBG) is proposed and experimentally demonstrated. Thanks to the intrinsic property of the phase-shifted phase-only sampled FBG, the proposed approach has an unique advantage, enabling one to tune and switch all the wavelength lasing simultaneously. The obtained fiber laser has a stable output with more than 30 wavelengths lasing. The 3 dB linewidth is similar to 13 pm, the signal-to-noise ratio is larger than 50 clB, and the nonuniformity of the output is smaller than 7.4 dB.
