Passage and Guide

Photonic Interconnect Platform

At Lightmatter, we pull the future in. We deliver the full photonics roadmap, from OBO, NPO, CPO, and 3D Interposers to next-generation light sources, and the chips are sampling today.

With our Passage photonic interconnect platform, we push the frontier of both photonic link design and packaging technologies—delivering chips with record-breaking energy efficiency, bandwidth, and reliability.

To power all of that bandwidth, we deliver a fundamentally new kind of laser. Guide is Lightmatter’s first-of-its-kind ELS technology—a universal external light source designed for our own platform and the entire AI infrastructure industry.

Available Form Factors

On Board

L-Series OBO

10x pluggable bandwidth in an ultra-high-density, serviceable module. Retimer required for extreme reach.

Near Package

L-Series NPO

10x pluggable bandwidth at a fraction of the energy. Minimized latency with linear-drive architecture.

Co-Packaged

L-Series CPO

High-efficiency, high-bandwidth chips co-packaged closely with XPU and switches.

Interposer Co-Packaged

M-Series

The ultimate in energy efficiency, bandwidth density, and speed. Edgeless I/O architecture.

Product Family: External Light Sources (ELS)

Guide™

The missing piece of the photonic puzzle. Consolidating massive optical power into software-defined modules to enable unlimited scale.

ELS (External Light Source) is the successor to discrete laser solutions. Guide™ acts as the precision power plant for the Zettascale era.
