The hydrodynamic approach based on the carrier concentration and velocity conservation equations is used to investigate the influence of photo-excitation of plasma waves at the beating frequency of two lasers on the intrinsic extra noise in InGaAs HEMTs caused by thermally-induced plasma oscillations. It is found that, by increasing the amplitude of the photo-excitation, a significant supression of the intrinsic excess noise is observed at the beating frequency as well as at all the frequencies where plasma waves can be excited.
