摘要

The nonlinear optical coefficientdij(kl)(2ω, 0,ω, ω)for electric field-induced optical second harmonic generation in semiconductors is calculated by means of a perturbation treatment. The result is given directly as a Brillouin zone integral over a resonant energy denominator. A simplified energy band structure model is used to carry out the Brillouin zone integral. The analytic closed-form expression fordij(kl)(2ω, 0,ω, ω)thus obtained permits the calculation of the absolute value of its spectrum from available energy band parameters. The dispersion ofd11(11)(2ω, 0,ω, ω)of Ge is numerically calculated, second harmonic photon energies being close to theE0andE1gaps. The results show pronounced resonant be
