  • Abstract
    Characteristics of a DFB laser under high-speed direct modulation are studied with an emphasis on the spectral analysis. A stable single-longitudinal-mode oscillation was confirmed up to 8.4 GHz direct modulation. The possibility of reducing the frequency chirping by device parameter optimisation is predicted on the basis of the experimental results obtained.
