Abstract:
This letter presents a broadband, high-optical modulation amplitude (OMA) GaN-based 1-to-N VCSEL driver implemented in a 150-nm GaN HEMT process for parallel and wireless optical transmitter frontends. It further compares split-node and conventional VCSEL-driving topologies and analyzes the bandwidth scaling and inter-VCSEL timing skew of series- and parallel-connected VCSEL arrays. …
