Session

Weekday Session 11: Communications

Location

Utah State University, Logan, UT

Abstract

To evaluate the performance change of Photonic integrated circuits after real cosmic radiation, silicon Mach-Zehnder Modulators were mounted on International Space Station on Low Earth Orbit for 6 months’ radiation harshness. Measured data of the device before and after radiation showed the permanent change of the effective index (around 10-3), the reduced carrier recombination lifetime, and the extended high speed bandwidth.
