    Abstract

    Two-section Fabry-Perot laser diodes can produce tunable radio frequency (rf)/microwave intensity oscillations (subcarrier) on the optical carrier without any active rf/microwave components. The frequency of the subcarrier is limited to a few Gigahertz for the free-running two-section Fabry-Perot laser diodes. A method for enhancing the frequency of the optically-generated subcarriers by using external optical injection is analyzed and demonstrated experimentally. It is shown that external optical injection can increase the effective tuning range: by 70%, in the meantime reducing the power in the high-order harmonics. (C) 1999 Elsevier Science B.V.
