Abstract

The present invention relates to a photomixer for generating terahertz electromagnetic radiation in response to illumination by a time-modulated optical signal. The photomixer (300) comprises a carrier substrate (310) with a plurality of quantum dots arranged in an emission region (308) thereof. A laser cavity (not shown) is arranged around the emission region of the carrier substrate (310) and an incident light (303) passage is adapted to directing the time-modulated optical signal to the emission region (308). Stimulated emission via the laser cavity is induced in the emission region (308) such that recombination of trapped electrons and holes in the plurality of quantum dots is accelerated to efficiently deplete the trap states.
