Abstract :
Requirements on quantum-dot crystals for 10-40 GHz-modulation bandwidth are clarified based on the understanding obtained by small-signal experiments and rate-equation analyses of 1.3-micron quantum-dot lasers, where carrier-capture process plays a significant role via K-factor-limited maximum bandwidth.
