Abstract :
Based on the double exposure technology, a novel dual-wavelength distributed feedback (DFB) fiber laser with a wavelength spacing of 400pm is proposed and experimentally demonstrated. By employing an equivalent phase shift, only a submicrometer-level precision is required in the fabrication for realizing precise phase control.
