Design and characterization of a silicon photonics transceiver chip enables high bandwidth and low energy use for die-to-die connections.
Embedded silicon photonics (SiPh) is promising to enable ultra-high bandwidth system-wide connectivity with vastly reduced energy consumption by integrating optics deeply within computing sockets. We present the design and characterization of a dense wavelength-division multiplexing (DWDM) SiPh transceiver chip, featuring a unique architecture in the multi-FSR regime and targeting a shoreline bandwidth density of 2 Tbps/mm with a sub-pJ/b energy consumption, providing a viable path toward die-to-die connectivity at scale.
