AI-Driven Optical System Design

Photonium automates optical system design. Think of us as Cadence or Synopsys chip design automation, but for optics instead of semiconductors. We handle the full design workflow—from optimization and verification to sourcing—for industries including quantum, biomedical imaging, LiDAR for autonomous vehicles and defense, and metrology for semiconductor fabrication.

Hey YC!

We’re Jennifer and Adam - cofounders of Photonium.

TL;DR

Photonium automates optical system design with AI, replacing costly manual iteration with end-to-end system optimization.

🚨 The Problem

Optical systems are mission-critical across many high-growth sectors — including quantum technology, biomedical imaging, LiDAR for defense and autonomous vehicles, and metrology for semiconductor fabrication.

But designing them is a nightmare:

  • Companies pour millions into teams of 20+ optical engineers
  • Projects take months or years to go from R&D to production
  • Tools are fragmented and outdated
  • Optimization is manual and often based on trial-and-error

Engineers spend countless hours on repetitive workflows — constrained by tools that haven’t changed in decades.

⚙️ Our Solution

Photonium is building the electronic design automation (semiconductor EDA) for optics. We work with complex optical setups across industries and handle the entire design process — from system generation and optimization to simulation, tolerancing, and sourcing.

Photonium enables companies to:

  • Generate and optimize designs from product specs
  • Predict tolerance impacts without slow simulations
  • Recommend data-driven alignment and manufacturing tweaks
  • Optimize for cost, size, and performance trade-offs
  • Seamlessly integrate with existing CAD workflows and optics simulation tools
  • Automate the full design-to-sourcing pipeline

🚀 The Team

Jennifer studied physics, math, and CS at Harvard and built quantum optics experiments across Harvard, Stanford, and QuEra (a Google-backed quantum computing startup).

Adam studied computational physics at Stanford, and worked on plasma simulation for fusion and large-scale astrophysical modeling of black holes.

We’ve both felt the pain of inefficient engineering design firsthand — and built Photonium to fix it.

⚛️ Why This Matters

Optical systems are foundational to cutting-edge technologies, from quantum computing to semiconductor fabrication. Yet, outdated tools and fragmented workflows slow innovation and inflate costs. We hope to eliminate these bottlenecks and accelerate innovation across industries.
