Abstract: This work presents a 48-Gb/s PAM4 optical receiver with TIA and sampler integrated. The TIA employs transadmittance transimpedance (TAS-TIS) structure to replace conventional CML-based VGA ...

Abstract: We report on a high-performance oxide-confined 850-nm vertical-cavity surface-emitting laser (VCSEL) believed to have the highest modulation bandwidth at low bias currents for datacenter ...
