Research output: Chapter in Book/Report/Conference proceedingConference contribution


We constructed a space-time phase modulated metasurface consisting of amorphous silicon building blocks, and demonstrated nonreciprocal light reflection at wavelengths around 860 nm. Our approach paves a way for miniaturized on-chip nonreciprocal optical components.
