Abstract
We numerically and experimentally study the effect of cavity dispersion in actively mode-locked ring lasers. The wavelength-swept laser with quite narrow linewidth is achieved by the combination of anomalous dispersion in a linearly chirped fiber Bragg grating and self-phase modulation-induced spectral broadening in semiconductor optical amplifier. By using this technique, a wavelength sweeping with rate of 120 kHz and range of 40 nm have been successfully demonstrated.
