中文摘要	The observation of intervalence subband transitions induced third-order nonlinear effect in Si1-xGex/Si multiple quantum wells was reported. The de Kerr in a symmetric quantum well, in which the linear-electro-optic effect is absent, was measured. The spectra of the absorption coefficient changes Delta alpha under external held was obtained using experimental Fourier transform infrared absorption data. The resulting changes of refractive index due to quantum-confined Stark effect was obtained by Kramers-Kronig relations based on measured absorption data. Moreover, under both 45 degrees incident angle and normal incidence, TE-active transition was excited and corresponding changes of refractive index under de field was observed. The measured large changes of refractive index make Si1-xGex/Si multiple quantum wells quite attractive for potential application in electro-optic devices such as modulators and switches.
