Quantum dot (QD) lasers have enormous potential for on-chip silicon light sources. Low threshold and reliable operation of InAs QD lasers monolithically grown on an on-axis (001) Si substrate have been demonstrated. Though direct modulation of QD laser on Si has been performed for bonded integration platform, there has been no report on direct-modulation properties of QD lasers epitaxially grown on Si. Here, we report the first demonstration of a direct-modulation of QD laser grown on Si. As a result, 12.5 Gbit/s direct modulation was successfully achieved.
