200-Gbps Directly Modulated 1060 nm Single-Mode VCSEL with Metal-aperture Coupled Cavity Achieving a Record Data-rate and Link-length Product of 400-Gbps·km

Puntos clave

This achievement enables 200-Gbps data transmission over a distance of 2 km, using single-mode fiber.
200-Gbps direct modulation was achieved through the incorporation of highly-strained InGaAs/GaAsP quantum wells.
The use of a metal-aperture coupled cavity significantly enhances performance in transmission applications.
Receiver DSP advancements facilitate efficient data handling at high transmission rates.

Resumen

We demonstrate 200-Gbps direct modulation of 1060-nm single-mode VCSELs incorporating intra-cavity metal-aperture and highly-strained InGaAs/GaAsP quantum wells. This achievement enables 200-Gbps PAM4 data transmission over 2-km standard single-mode fiber, facilitated by advanced receiver DSP.
