Optical phenomena in spatially structured composite materials have attracted attention to the areas at intersection of optics and condensed matter physics—photonics and plasmonics. That caused the development of studies of the composites’ properties and methods of their characteristics’ visualization. The spectroscopy of aperiodic structures and the methods of controlling their properties by means of the interaction of light with a composite material are of increased interest and relevant. The goal of this study is the development of metal–dielectric composite based on thin layers of copper and amorphous carbon (à-Ñ), determination and controlling of the parameters of the resonance phenomena in composite. Metal–dielectric composites based on amorphous-carbon thin layers deposited on a copper layer over a glass substrate are used as samples. A thin film of iron metallophthalocyanine (FePc) is used as an analyte. The composite layers are obtained by means of the sequential thermal spraying in a vacuum using the PC controlled vacuum machine VUP-5M. Using the methods of optical spectroscopy in a visible range and Raman scattering, the composite reaction on non-thermal irradiation is studied. As a result, the parameters of the copper layer are optimized (R=8 $$\Omega$$), and the possibility of controlling the resonance properties of the composite layers by means of the light irradiation is shown. The amplification of the Raman spectra of an analyte in a metal–dielectric composite is obtained.
