摘要

In this paper we demonstrate an interleaved waveband switching in a fiber ring laser incorporating a semiconductor optical amplifier as a gain medium and a polarization-independent interleaving filter based on a polarization-diversity loop structure as a wavelength-selective element. The interleaver consists of a polarization beam splitter, high birefringence fibers, and half-wave plates. By employing the interleaver, multiwavelength switching operation of up to 19 laser lines with the signal to noise ratio over 30 dB and 0.8 nm wavelength spacing, whose switching displacement was 0.4 nm, has been successfully demonstrated at room temperature.
