Abstract

We introduce and demonstrate an integrated nonlinear splitter in quasi-phase matched lithium niobate nanophotonic waveguide featuring femtojoule all-optical switching with instantaneous response and 8.5 dB extinction, opening opportunities for on-chip ultrafast energy-efficient all-optical information processing.
