Problem
Data centers and high‑performance computing systems are constrained by the limited bandwidth, high latency, and excessive power consumption of traditional copper‑based electrical interconnects. Scaling these systems with purely electronic chips leads to thermal challenges and slower data transfer rates, hindering performance growth.
Solution
Black Semiconductor provides wafer‑scale, single‑crystal graphene integrated photonics (IGP™) that combines optical and electronic functions on a single CMOS‑compatible chip. By leveraging graphene’s ultrafast carrier dynamics, the technology converts electrical signals to optical signals instantly, enabling low‑loss, high‑speed data transmission directly on the wafer. Optical waveguides replace copper interconnects, reducing latency and energy use while increasing bandwidth. The graphene layers are grown via epitaxial chemical vapor deposition and transferred using a proprietary, CMOS‑friendly process, allowing seamless integration into existing semiconductor manufacturing lines. This approach delivers faster, cooler, and more energy‑efficient chips suitable for next‑generation data‑center and HPC applications.
