1. Apparatus for providing a photoconductive response to optical excitation, comprising:
an all-dielectric metasurface disposed on a substrate surface; and
an electrode arrangement electrically connected to the all-dielectric metasurface, wherein:
the all-dielectric metasurface comprises an array of dielectric Mie resonators;
the Mie resonators incorporate features that collectively interconnect the Mie resonators in a network that carries electric current when in operation; and
the features that collectively interconnect the Mie resonators have a configuration that prevents the Mie resonators in which they are incorporated from having more than one symmetry plane normal to the substrate surface.
