We evaluated the radiation effects of cosmic rays on silicon Mach-Zehnder Modulator loaded on International Space Station. Permanent changes of refractive index (10-3) and carrier lifetime reduction have been observed after 6 months’ radiation.

The accumulative radiation increases the defects density in silicon and reduces the free-carrier lifetime, which results in reduced photo-thermal dispersion in silicon micro-ring resonators.

Models of quantum systems on curved space-times lack sufficient experimental verification. Some speculative theories suggest that quantum correlations, such as entanglement, may exhibit different behavior to purely classical correlations in curved sp
