Abstract

Compact optical elements capable of admitting/rejecting light from a specific direction(s) are key components of integrated systems for all-optical imaging processing, wavefront manipulation, optical communication in turbid media and optical metrology (and LIDARs in particular). The existing solutions based on spatially dispersive structures, such as photonic crystal slabs, resonant gratings, and perforated films exhibiting extraordinary transmission, all suffer from diffraction into multipole orders, while angular dependence of their response is complicated by consistent large wavelength shifts of the relevant spectral features [1], [2]. Similar behaviour (although in the absence of multipole diffraction orders) is characteristic of recently demonstrated non-diffracting wavevector selective metasurfaces [3], [4]. Here we identify and investigate a new, special class of such metasurfaces, in which the optical transmission spectra exhibit a strong amplitude correlation with the angle of incidence with the relevant changes confined to a very narrow wavelength range.
