In-package optical I/O — a complete, housed, chip-to-chip communication interconnect using light instead of copper.
Integrated photonics — a technology that brings together light sources and guides to create a circuit.
Lambda — the wavelength of light, which is the distance between two peaks of a wave.
Microring resonators — a looped method for guiding light within a small footprint (nanometer scale).
Moore’s Law — Gordon Moore’s observation that the number of transistors on a chip would double every two years.
Multi-chip package (MCP) (or MCM — multi-chip module) — an assembly of multiple integrated circuits (chips) to create a larger integrated circuit or chip.
Optical interconnects — a way of sending signals from one part of an integrated circuit to another using light.
Photonic integrated circuit (PIC) — an electronic circuit that uses optical components, such as waveguides, modulators, and lasers, all on a single chip.
