Abstract
We demonstrate < 6× modulation bandwidth extension of a heterogeneous quantum-dot microring laser using optical injection locking, obtaining 18 Gb/s on-off-keying modulation with clear open eyes. Single-mode lasing of all 11 longitudinal modes were achieved with <44 dB side-mode suppression and minimal 5 dB power increase.
