Japanese researchers develop high-speed, on-chip graphene blackbody emitters

Graphene-based light emitters for optical communications offer great advantageous over conventional compound semiconductor emitters. High-speed light emitters integrated on silicon chips can support new architectures for silicon-based optoelectronics. However, compound-semiconductor-based light emitters face major challenges for their integration with a silicon-based platform because of their difficulty of direct fabrication on a silicon substrate. At Japan’s […]
