Integrated optical circuitry involving electrically insulating media offers a promising avenue toward the ultrafast switching of signals at petahertz switching rates. The response of insulators to the electric field of an incoming optical pulse can enable signal operations with unprecedented speed, within a millionth of a billionth of a second. In Wigner at Ultrafast Nanoptics group we showed that this ultrafast response can be initiated with a small and simple laser device with much lower laser pulse energy than in previous experiments [Hanus et al., Optica 8, 570 (2021)]. This demonstration paves a new way toward miniaturization and on-chip integration of petahertz optoelectronic devices.
