Co-packaged optics represents an advanced integration approach that combines optical components with electronic devices in a single package, placing optical interfaces directly alongside electronic switching or processing elements to overcome bandwidth, power consumption, and density limitations of traditional electrical interconnects. This sophisticated technology leverages photonic integration, advanced packaging techniques, and novel optical coupling methods to enable high-bandwidth data movement with dramatically improved energy efficiency, creating new possibilities for data center networks, high-performance computing, and telecommunications infrastructure.
Unlike conventional architectures where optical transceivers connect to electronic switches through relatively long electrical traces on printed circuit boards, co-packaged optics minimizes the distance that high-speed electrical signals must travel by integrating optical engines directly within or immediately adjacent to switch or processor packages. This fundamental redesign addresses the physics-based challenges of electrical signaling at very high data rates, where signal integrity degradation and power consumption become prohibitive beyond certain speeds and distances, potentially enabling the continued scaling of system bandwidth while simultaneously improving energy efficiency—critical requirements for next-generation computing and communication systems.
