Abstract

We theoretically study the carrier frequency down-conversion from optical signals to terahertz signals utilizing two-dimensional plasmons in an InGaAs-channel high-electron-mobility transistor (InGaAs-HEMT). We demonstrate that the down-conversion can be implemented by the so-called photonic double-mixing functionality in the HEMT utilizing the plasmonic hydrodynamic nonlinearities and that the double-mixing conversion gain can be enhanced by orders of magnitude with the help of the plasmon-resonance effect.
