Photon Design is a software development company based in Oxford, England, that has supplied photonics simulation software since 1992. Its offerings span modeling laser diodes and photonic integrated circuits as well as Maxwell equation solvers for simulating optical components. With extensive experience in photonics design and numerical methods, the firm serves researchers and industry professionals seeking rigorous modelling capabilities. The organization operates as a small to mid-sized team focused on specialized software for photonics. In 2026, Photon Design launched HAROLD QD, a quantum dot laser simulation tool that enables modeling of multi-layer epitaxy structures. That year it also formed a partnership with Cardiff University to deliver a two-day laser design course as part of the physics curriculum.
