✦ Synopsis
The high-order harmonics generation in bulk InN, subjected to a high-frequency alternating electric field of strong-amplitude is investigated theoretically using Monte Carlo simulations of carrier interacting with a multi-mode electric field. This approach allows on the one hand to account in a natural way for the effect of the reabsorption of the generated radiation by the nonlinear medium itself, and on the other hand to estimate the constraints, which must be satisfied by the external experimental setup to achieve the maximum conversion efficiency. It is demonstrated, that InN is a promising material for such a conversion up to the THz frequency range. Under optimum conditions, the power conversion efficiency is found to reach several percents.
