Our study aims at evaluating the radiation sensitivity of this technology which needs to be progressed to expedite the adoption of PICs for space applications. The following approach is to irradiate a PIC-based COTS device, (a narrow linewidth tunable laser source) that is composed of several building blocks of which we aim to determine radiation sensitivity

Quantum communication systems have revolutionized the security of the encryption keys distribution, thanks to the unique property of having the ability to detect if a third person has tried to obtain the key (eavesdropper’s detectability) and, thus, break the line communication to preserve the message. This method of communication is called Quantum Key Distribution.
