Abstract
A novel multiwavelength fibre laser is proposed which is based on a fibre loop mirror formed by a high-birefringence (HiBi) fibre a polarization controller, and a directional coupler. By setting the polarization controller properly, the HiBi fibre loop mirror acts as a polarization-independent wavelength filter. With this configuration, the wavelength spacing of the laser can be varied accurately by adjusting the length of the HiBi fibre. Experimentally, by cooling the erbium-doped fibre with liquid nitrogen to reduce its homogeneous linewidth, stable emission at 16 wavelengths with a spacing of 0.8 nm and an amplitude variation of
