The development of color routers (CRs) realizes the splitting of dichromatic components
contributing to the modulation of photon momentum that acts as the information carrier for optical information technology on the frequency and spatial domains. However
CRs with optical stimulation lack active control of photon momentum at deep subwavelength scale because of the optical diffraction limit. Here
we experimentally demonstrate an active manipulation of dichromatic photon momentum at a deep subwavelength scale via electron-induced CRs
where the CRs radiation patterns are manipulated by steering the electron impact position within 60 nm in a single nanoantenna unit. Moreover
an encrypted display device based on programmable modulation of the CR array is designed and implemented. This approach with enhanced security
large information capacity
and high-level integration at a deep subwavelength scale may find applications in photonic devices and emerging areas in quantum information technologies.
