    "abstract": "An undoped double quantum well (DQW) was driven with a terahertz (THz)\nelectric field of frequency \\omega_{THz} polarized in the growth direction,\nwhile simultaneously illuminated with a near-infrared (NIR) laser at frequency\n\\omega_{NIR}. The intensity of NIR upconverted sidebands\n\\omega_{sideband}=\\omega_{NIR} + \\omega_{THz} was maximized when a dc voltage\napplied in the growth direction tuned the excitonic states into resonance with\nboth the THz and NIR fields. There was no detectable upconversion far from\nresonance. The results demonstrate the possibility of using gated DQW devices\nfor all-optical wavelength shifting between optical communication channels\nseparated by up to a few THz.",
