Data centers consume ~2% of total electricity—and that share is growing rapidly.
Iris Light Technologies is developing a tunable laser that can be printed directly onto semiconductor chips for improved data center efficiency. Their manufacturing process is compatible with existing chipfab—multiple lasers can be integrated directly onto the chip at low cost. These lasers are used for fiber optic data transfer, which improves energy efficiency compared with copper interconnects and allows better utilization of memory, storage, computation, and other data center components. Iris Light is an Argonne National Lab spinout that is also part of the Chain Reaction Innovations Incubator.
