A plasmonic photonic diode for unidirectional focusing, imaging, and wavelength‐division de‐multiplexing is achieved through the holographic imprinting of a discrete optical lens into metallic photonic crystals (MPCs). X. P. Zhang et al. focus laser beams of different colors to different angles and different focal lengths with a large dispersion using such a thin‐film device. Realization of such functions is based on the spatial chirping of the MPCs, where the gold nanolines are arranged with different periods on different sites of the device.
