摘 要: | Theoretical work on the optical properties of the one-dimensional dielectric superlattice is extended.By means of a transfer matrix method,the second-harmonic and third-harmonic generations in a one-dimensional finite Thue-Morse dielectric superlattice are analysed.The electric field amplitude variables of the second-harmonic and third-harmonic can be expressed by the formula of matrices.taking advantage of numerical procedure,we discuss the dependence of the second-harmonic and third-harmonic on the fundamental wavelength and the field amplitude variables of the fundamental wave.High conversion efficiency of the third-harmonic can be obtained at some special fundamental wavelength.
