FRESCO: FREquency Stabilized Coherent Optical Low-Energy WDM DC Interconnects
The University of California-Santa Barbara will develop a low power, low-cost solution to overcome power and bandwidth scaling limitations facing hyperscale data centers and exponential growth in global data traffic. The FRESCO transceiver leverages advances in fundamental laser physics and photonic integration to enable terabit, coherent optical data transmission inside data centers through chip-scale spectrally pure and ultra-stable wavelength division multiplexed laser light sources . The project outcome will be an integrated photonic package capable of connecting to 100 terabit-per-second networking switches over coherent optical short-reach data center fiber links. This effort could transform the way data centers, data center interconnects, and terabit Ethernet switches are built, drastically reducing their global energy consumption.
The University of California-Santa Barbara will enable 102.4 trillion bits per second (Tbps) transmitted over multiple light wavelengths in the data center interconnect (DCI). This project will facilitate 10 times more energy efficiency, 10 times less cost and complexity over current data transmission technologies, and:
