Integrated Waveguide-Grating-Coupled VCSEL/Photodetector Arrays with High Coupled Power for Dense High-Speed Interconnects

Integrated waveguide-grating-coupled VCSEL/RCEPD arrays with >1.4 mW/facet output power and VCSEL-to-photodetector data communication at >1.25 Gbps through an integrated waveguide have been demonstrated. This technology will enable practical applications using VCSEL-based photonic integrated circuits.
