About Photonium

Photonium is building the next-generation design automation platform for optical systems, using AI to automate the entire optical design process—from layout generation and optimization to simulation, tolerancing, and sourcing. It positions itself as a next-generation alternative to traditional optical design tools, described as "like Cadence or Synopsys, but for optics." The company is backed by Y Combinator (X25) and is part of the NVIDIA Inception program, reflecting its early-stage support and industry backing. Founded by a team of physicists and engineers who have experienced the pain points of optical design, Photonium's mission is to fix slow and expensive manual workflows by automating the design process with AI. Its focus spans optical system design for quantum computing, biomedical imaging, LiDAR, and semiconductor manufacturing, as it builds intuitive tools and intelligent automation to help engineers design faster and cheaper.
