What Photon Design does

Photon Design is a UK-based, privately held software company founded in 1992 and headquartered in Oxford, specializing in photonic simulation CAD software for the photonics industry. The company builds simulation tools that enable engineers to model and design photonic integrated circuits (PICs), including passive and active optical components, quantum dot lasers, silicon modulators, waveguide components, and emerging device types such as TFLN Mach-Zehnder modulators and PCSELs. Its core products are HAROLD QD (a quantum dot laser simulator targeting silicon-platform laser design for data center, AI, and HPC applications) and PICWave (a photonic IC design and simulation environment that received a GUI and capability update in late 2025), supported by modular tools such as MT-FIMMPROP for TFLN Mach-Zehnder modulator designs, a silicon modulator design tool, waveguide simulation tools, a quantum dot module, and a PCSEL solution.

The company generates revenue through software licensing of these simulation tools to photonic IC designers and engineers, with the licensing model described as recurring/subscription-based and distribution conducted via direct enterprise licensing on a global basis. Go-to-market is event-driven: Photon Design showcases its product suite at major industry conferences including OFC (Optical Fiber Communication Conference, e.g., OFC 2026 in Los Angeles) and the Optica Laser Congress and Exhibition. Its primary customer segments, by use case, are data center operators, AI/ML companies, HPC applications, and LiDAR system developers — all of which require advanced optical components where simulation reduces physical prototyping cost and time. Photon Design presents itself as a global leader in photonic simulation CAD, though publicly verifiable customer logos, revenue figures, funding history, and headcount trends are not available in the source data.
