Startup Tackles AI Hardware Limits with Innovative Optical Materials, Secures $80M Funding

AI’s growth is being held back not by chips, but by the copper wiring connecting thousands of GPUs. As AI clusters expand, traditional copper links are proving inadequate for data transfer demands. HyperLight, a startup emerged from Harvard research, is developing new optical materials to replace copper wiring, pushing data through light and overcoming current bottlenecks.
