A long-distance ranging system with chip-scale integration potential is developed using soliton pulses generated from an on-chip microcavity, and high-speed, highly accurate and real-time ranging is experimentally demonstrated at long distance of more than 1179 m.
We present theoretically the formation of exciton–photon polaritons and exciton-surface plasmon polaritons in a perovskite-based subwavelength lattice on the metallic plane. It is shown that the later polaritons will be achi
