Problem
Photonic integrated circuits (PICs) with high performance often rely on single-material platforms, leading to high optical losses, limited functionality, and supply‑chain constraints when scaling to complex applications such as quantum computing, AI accelerators, and advanced defense systems.
Solution
Light Integration Technologies (LIT) creates a multifunctional photonic platform that combines ultra‑low‑loss waveguides with heterogeneous integration of best‑in‑class materials—including III‑V semiconductors, lithium niobate, piezo‑MEMS, liquid crystals, and phase‑change media. By embedding lasers, amplifiers, detectors, modulators, magnetless isolators, switches, memory elements, and electronic beam‑control circuitry on a single chip, the platform delivers laboratory‑grade performance while remaining manufacturable at scale. The approach is designed to support demanding markets and to maintain a robust supply chain as production volumes increase.
Target Audience
Primary customers are manufacturers of quantum hardware, AI accelerator systems, high‑performance consumer electronics, and defense photonic subsystems that require densely integrated, low‑loss optical components.
