Abstract

A systematic microscopic theory is presented for high-harmonic generation in III–V semiconductors that are excited by strongly detuned high-intensity electromagnetic pulses. As a mechanism for the appearance of even harmonic orders, the quantum interference of different transition paths is analyzed. For the binary zinc-blende semiconductors, InAs, InP, and GaAs, the intensity ratio between even- and odd-order harmonic emission depends on the strength of the respective intervalence band dipole coupling. However, the large intervalence band dipole in InP leads to even and odd harmonics of similar intensity, no or only very minor even-order emission due to quantum interference is predicted for InAs where the fundamental transition is strongly favored over intervalence band transitions.
