Data envelopes are sent via electrically controlled transmitters through an optical cross-connect router to burst-mode receivers. ICCOS can route the light to any output port through a non-blocking dense wavelength-division multiplexing cross-connect router.

Biomimetic Integrated Optical Sensor

For the Air Force, Luminit developed a new Biomimetic Integrated Optical Sensor (BIOS) system. The system is based on the unique integration of a wide field-of-view (FOV) miniature staring multi-aperture compound eye with a high-speed, low-cost, polarization and spectral selective liquid crystal (LC) filter array, a focal plane array (FPA), and a neural network processor. The BIOS system will use most if not all of the information in the light field, including spectral, temporal, polarization, and intensity for detailed object shape, for applications enabling autonomous behavior, including egomotion determination, to aid in navigation; as well as target detection, recognition, ranging, and tracking.

Ferroelectric Photogalvanic Generator

Luminit is developing anew Ferroelectric Photogalvanic Generator (FEPG), based on the Photogalvanic (giant photovoltaic) effect. FEPG consists of two blocks (removable for easy maintenance): 1. Pulsed light source, and 2. Ferroelectric cell. Power supplies may be diverse: an explosion-driven light source and battery-operated flash lamps could be used. If operated in deserts or in places with plenty of sunlight, concentrated sun radiation with a chopped window can be used as a power source. The major innovation in the FEPG is the use of a new physical principle of high-voltage generation, based on relatively new giant photovoltaic effect (GPE), or the photogalvanic effect.
