Abstract
A theoretically perfectly absorbing photoconductive all-dielectric metasurface is provided. This metasurface can improve the efficiency and performance of ultrafast photoconductive switches and detectors. In an embodiment, the metasurface is incorporated in photoconductive THz switches or detectors. In embodiments, the metasurface is constituted by a network of gallium arsenide resonators. Each resonator supports two degenerate and critically coupled magnetic dipole modes. Simultaneous excitation of these two modes leads to theoretically close-to-perfect optical absorption near the resonant wavelength.
