Abstract :
A three channel-spacing tunable multiwavelength fiber ring laser by using two segments of polarization-maintaining fiber (PMF) is experimentally demonstrated. By adjusting the polarization controllers, the wavelength spacing could be efficiently switched among 0.48, 0.73, and 1.45 nm. Moreover, we also analyzed theoretically the equivalent Lyot birefringence fiber filter with two segments of PMF. Theoretical prediction was verified by experimentally obtained multiwavelength outputs.
