Compact, physics-aligned modeling tools.

We develop specialist tooling for integrated photonics, with an eye toward quantum-adjacent systems. Focused on bridging the gap between Meep-level simulation and yield-driven manufacturing.

Active Project

PROOF OF CONCEPT

C³-Photonics

Arrived here from c3photonics.com? C³-Photonics is an active Determiq R&D project.

A local photonic coupler yield & tolerance assistant. It targets the “black box” problem of coupling efficiency by calibrating directly from small simulated or measured datasets.

  • Calibrates from small IL datasets (e.g., Meep/Lumerical exports).
  • Generates misalignment IL maps in real time, without FDTD reruns.
  • Estimates spec → yield curves & guardbands from the calibrated model.

CURRENT STATUS

Seeking external validation with academic and industry partners on simulated and measured coupler datasets. Not yet released for public production use.
