PASSAGE™ L200

First Edgeless I/O 3D Co-Packaged Optics.

Passage L200 eliminates the shoreline bottleneck. By stacking the photonic engine vertically with the electronic IC, we deliver 32-64 Tbps of optical I/O per chip—enabling bandwidth densities 5-10× greater than conventional solution.

Breaking the Shoreline Constraint

The Problem

Conventional chip I/O is confined to the die edges (“shoreline”). As die area scales (r²), perimeter only scales linearly (2πr).

This geometry creates a bandwidth bottleneck: chips run out of edge space long before they run out of compute capability.

The 200 Solution

Edgeless I/O Architecture. We vertically stack the photonic IC (PIC) underneath the electronic IC (EIC).

This allows SerDes to be positioned anywhere across the entire die area, effectively unlocking unlimited bandwidth density scaling.
