Problem
Designing and manufacturing photonic integrated circuits (PICs) on thin‑film lithium niobate (TFLN) requires specialized, high‑volume fabrication facilities that can deliver low‑voltage, high‑speed modulation and strong nonlinear performance. Existing foundries often lack the process maturity, wafer size, or design kits needed for production‑grade TFLN devices, leading to long development cycles and high risk for manufacturers.
Solution
Lightium operates a production‑grade photonic foundry that fabricates 200 mm TFLN wafers in a high‑volume environment, enabling rapid prototyping through to volume production. The company provides a comprehensive process design kit (PDK) covering multiple wavelength bands (C‑band, O‑band, 780 nm, 830 nm) and supports the intrinsic advantages of TFLN, such as >100 GHz light‑speed modulation, sub‑1 V drive voltage, a broad transparency window (350 nm–5.5 µm), and strong second‑ and third‑order nonlinearities. By offering a closed‑beta access model, Lightium reduces time‑to‑market and industrialization risk for customers developing next‑generation photonic solutions.
Target Audience
Primary customers are photonic chip designers, semiconductor manufacturers, and system integrators developing high‑speed, low‑power, or nonlinear optical components for data‑center, telecom, and emerging quantum or sensing markets.
