The studies on the properties of the spectral peaks for the second harmonic light through the ferroelectric domains constructed following the Fibonacci-class quasilattice sequence

On the basis of a brief presentation of the characteristic for the Fibonacc i-class quasilattices (FC(n)), the properties of the spectra were studied f ar the second harmonic light (SHL) through the N layers ferroelectric super lattices constructed following FC(n) by means of the small-signal approxima tion. It was found that in the real space there existed perfect self-simila rity for the most intense spectral peaks of SHL. On the other hand,the self -similarity for the spectra will. be broken if the refractive dispersion is taken into account. The effect of vacancies which was valid only for the S HL's dim spectra lines but invalid for the bright ones is also discussed.
