OptixLog builds infrastructure software for photonics and semiconductor engineering teams. We connect design data, PDK and process information, fabrication runs, metrology, and characterization results into one structured system so engineers can trace how device performance changes across the full design-to-fab-to-test cycle. By organizing simulation, layout, wafer, process, and measurement data in one place, OptixLog makes root-cause analysis faster, preserves engineering knowledge across teams, and enables AI to work on structured technical data instead of disconnected files and spreadsheets.
