Abstract:
The investigation of second-harmonic generation in a one-dimensional photonic crystal was carried out. The calculation of the $\chi^{(2)}$ – grating recording in a periodic system consisted of air and glass layers and second-harmonic generation in it was performed. The frequency conversion efficiency at different wavelengths of the first harmonic was estimated.
Keywords:one-dimensional photonic crystal, second harmonic generation, optical nonlinearity, conversion efficiency.
