Query: Cryogenic operation of silicon photonic modulators based on DC Kerr
  effect   Reliable operation of photonic integrated circuits at cryogenic temperatures
would enable new capabilities for emerging computing platforms, such as quantum
technologies and low-power cryogenic computing. The silicon-on-insulator
platform is a highly promising approach to developing large-scale photonic
integrated circuits due to its exceptional manufacturability, CMOS
compatibility and high component density. Fast, efficient and low-loss
modulation at cryogenic temperatures in silicon, however, remains an
outstanding challenge, particularly without the addition of exotic nonlinear
optical materials. In this paper, we demonstrate DC-Kerr-effect-based
modulation at a temperature of 5 K at GHz speeds, in a silicon photonic device
fabricated exclusively within a CMOS process. This work opens up the path for
the integration of DC Kerr modulators in large-scale photonic integrated
circuits for emerging cryogenic classical and quantum computing applications.
