Abstract

The problem of enhancing the efficiency of detecting radiation in the long-wavelength part of the optical spectrum is considered. The second-harmonic generation in two-dimensional photonic crystals based on iodic acid is investigated in order to convert long-wave radiation into the visible range for subsequent detection by conventional silicon detectors. The problems of synthesis of two-dimensional photonic crystal structures for practical problems of nonlinear optics and photonics are discussed.
