2018 43rd International Conference on Infrared, Millimeter, and Terahertz Waves (IRMMW-THz).
In this communication, we propose a new architecture of photomixer in order to develop a wideband and powerful photomixing THz source. It is achieved by a velocity-matched distributed photoconductor (VMDP), in which the pump optical power is guided i
