Abstract

Precise observation of the single longitudinal mode spectrum for distributed feedback lasers revealed fine structures when the spectrum was broadened by high-speed modulation. A dynamic simulation can explain reasonably the above behavior if the model takes into account the carrier density modulation enhanced by the relaxation oscillation. In this work, experimental results where both modulation depth and speed were varied are described along with a calculated result.
