摘要

We propose a vertical-cavity surface-emitting laser (VCSEL) laterally coupled to multiple transverse cavities (MTCCs) providing modulation bandwidth beyond the relaxation-oscillation-frequency. We show a 3dB modulation bandwidth of 45 GHz, five times greater than it’s conventional VCSEL fabricated on the same epi-wafer.
