ALTER is performing gamma and proton radiation at various PICs. The satellite market is experiencing a paradigm shift with the photonics penetration in every part of the satellite payload. Although some advances have been done with the introduction of optical interconnects in a commercial digital processor of a satellite payload

The most relevant result of this work is that all tested samples passed satisfactory the test without relevant changes in the measured parameters, with the exception of one of the WG-EO switches which had a catastrophic failure, as it will be commented later. The pass/non-pass criteria were defined comparing the results of the electro-optical characterization after each test with the corresponding results for each parameter prior to the tests, taking into account the measurement uncertainty.

Photonic Encryption, Quantum communications offer many advantages for secure data transmission, such as confidentiality, integrity and spy detectability. Quantum physics allows the encoding of information using the correlation between two or more particles (photons, atoms) thanks to quantum cryptography or Quantum Key Distribution (QKD), a method of processing information arising from the properties of quantum entanglement.
