Abstract :
This presentation will begin by contrasting the LTG-GaAs photomixer against other solid-state generation techniques being pursued in the far-infrared region, including three-wave mixing and electronic frequency multiplication. The second part of the presentation will review recent experiments aimed at overcoming the efficiency limits and in achieving power levels above 1 μW. The final part of the presentation will focus on the implementation of the photomixer in scientific instruments for astronomy, chemistry, and metrology
