抄録

This paper introduces an innovative design for double-transverse-coupled-cavity (DTCC) VCSELs aimed at achieving high-speed modulations exceeding 21GHz with single mode operations. The lateral in-plane optical feedback across both cavities facilitates a significant enhancement in direct modulation bandwidths. Open eye diagrams were discerned for data rates as high as 36 Gbps (NRZ) and 48Gbps (PAM4).
