The filter is based on a fiber Bragg grating asymmetrically located in a Sagnac loop. Two filters with four band-passes and five band-passes, respectively, were fabricated and applied to an erbium-doped fiber ring laser. Stable four-wavelength and five-wavelength laser operations have been demon-strated.展开更多

Experiments indicate that polarization hole burning can be enhanced by the changes of optical MQW waveguide bias current and the polarization states in the laser cavity. Ten wavelengths with 0.9 nm spacing are generated at room temperature.展开更多
