Dispersive-grating distributed feedback lasers.
This paper proposed a novel distributed feedback (DFB) laser by incorporating a dispersive grating, whose coupling strength is dependent on the operating wavelength. Analysis of the laser threshold conditions shows that the proposed structure guarantees single-mode operation due to the inherent threshold gain discrimination on the two otherwise degenerated lasing modes.
