Abstract

Omitting the dispersion of side bands, the self-distortion of an amplitude-modulated e.m. signal due to non-linear polarizability in nonparabolic semiconductors has been investigated. The distortion is basically due to self-focusing of the electromagnetic wave and is different from the resistive (absorption) type demodulation.

In n-InSb and at average powers of ∼1 W the index of modulation is found to increase four times at a modulation frequency R~108 s−1.
