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