Abstract :
Two novelties have been exploited in developing high-speed directly-modulated distributed feedback and distributed Bragg reflector lasers: the use of surface gratings, to enable a single growth and processing sweep, and the use of photon-photon resonance, to enhance the direct modulation bandwidth beyond the limits set by the carrier-photon resonance.
