Conversion efficiency of second harmonic generation in onedimensional photonic crystal based from isotropic material

Аннотация:

The investigation of second-harmonic generation in a one-dimensional photonic crystal was carried out. The calculation of the χ (2) – grating recording in a periodic system consisted of air and glass layers and secondharmonic generation in it was performed. The frequency conversion efficiency at different wavelengths of the first harmonic was estimated.
