A NASA team plans to build the first integrated-photonics modem, using an emerging, potentially revolutionary technology that could transform everything from telecommunications, medical imaging, advanced manufacturing to national defense.

The cell phone-sized device incorporates optics-based functions, such as lasers, switches, and fiber-optic wires, onto a microchip similar to an integrated circuit found in all electronics hardware.

The device will be tested aboard the International Space Station beginning in 2020 as part of NASA’s multi-year Laser Communications Relay Demonstration (LCRD). The Integrated LCRD LEO (Low-Earth Orbit) User Modem and Amplifier (ILLUMA) will serve as a low-Earth-orbit terminal for NASA’s LCRD, demonstrating another capability for high-speed, laser-based communications.
