Abstract: Described herein is a novel approach that leverages a 3D stacked die complex with an active optical interposer integrated with an I/O chiplet including high-speed serializer/deserializer (SerDes). By integrating silicon in this way, shoreline constraints are eliminated, allowing for the SerDes macros to be placed virtually anywhere on the I/O chiplet. The photonic-based interconnects described herein improve upon conventional approaches based on co-packaged optics (CPO), Linear-drive Pluggable Optics (LPO) and copper-based solutions in terms of bandwidth and power consumption. The interconnects described herein rely on photonic-electronic packages in which a PIC provides processing units (e.g., XPU), electronic switching chips or other types of application-specific integrated circuits (ASIC) with access to optical fiber-based networks while multiple SerDes provide high-speed serialization and deserialization.

Abstract: Described herein are wavelength division multiplexing (WDM) transceivers configured to support fast, bidirectional communication over optical channels. An optical transceiver comprises a transmitter, a receiver, an input/output (I/O) port and an optical interleaver. The transmitter comprises a first bus waveguide and a plurality of optical modulators coupled to the first bus waveguide, each of the optical modulators being resonant at a respective wavelengths in a first wavelength set. The receiver comprises a second bus waveguide and a plurality of optical filters coupled to the second bus waveguide, each of the optical filters being resonant at a respective wavelength in a second wavelength set. The (I/O) port is coupled to an optical channel.
