Photonically controlled metastructures containing resonant conducting dipole and chiral elements with CdS and CdSe in gaps have been proposed, implemented, and studied in a waveguide and a meta-interferometer in the range of 3–12 GHz. It has been found experimentally for the first time that the variation of the optical radiation power Pλ guided by the optical fiber to the region of the discontinuity when the photon energy hν is both above the width of the band gap Eg [hν(λ1 = 0.53 μm) > Eg] and below it [hν(λ2 = 0.97 μm) < Eg] results in the transformation of the resonant response of the corresponding element (smooth variation of the intensity almost to the transparency level accompanied by a decrease in the frequency) in the microwave transmission spectrum, as well as in the transformation of the stopband in the interferogram of the meta-interferometer with a severalfold change in the width. In addition, under λ2 irradiation, orange–red luminescence identified as a manifestation of anti-Stokes luminescence is observed on the CdS surface. Direct cavity measurements of the complex permittivity εGHz of the CdS and CdSe samples have demonstrated an increase in both ImεGHz (with approaching saturation at λ2) and ReεGHz with increasing Pλ. Characteristics of the identical manifestation of physical effects at microwave frequencies under one- and two-photon excitation have been revealed in application to the light energy flux densities S1 (at Pλ1) and (at Pλ2):
