Abstract
Satellite-based optical quantum technologies represent a promising field for obtaining a worldwide quantum network. However, due to the limited size of satellites and the adverse conditions of a space environment, only compact and resistant devices can be used for this purpose. In this respect, we present for the first time the space qualification of integrated photonic circuits fabricated by Ultrafast Laser Writing. By inscribing different straight waveguides, directional couplers and Mach-Zehnder interferometer, and by exposing them to appropriate proton and gamma ray irradiations, we show that our integrated devices are suited for performing quantum experiments in a low Earth orbit.
