In this letter, we propose a novel multiwavelength-switchable fiber ring laser based on a semiconductor optical amplifier and reflection-type interleaver composed of a polarization-maintaining fiber (PMF) loop mirror and a polarization beam splitter. In the proposed fiber laser, stable interleaved waveband switching operation at up to 17 oscillating wavelengths with 0.8 nm spacing, whose switching displacement is 0.4 nm, is successfully demonstrated at room temperature by the proper control of the polarization controller within the PMF loop mirror.
