Idunn DILI is an all-in-one photonic instrumentation platform designed to drive, control, and characterize Photonic Integrated Circuits (PICs), DFB/DBR lasers, SOAs, and high-speed optical sources and detectors. The platform features an internal enclosure space (160 mm × 280 mm × 40 mm) that allows users to mount butterfly devices and PICs directly inside the instrument, drastically reducing external fiber interconnections and maximizing optical measurement stability.
