Abstract

A novel method for frequency conversion using a transmission line on a semiconductor substrate has been presented. Laser pulses move along the transmission line while generating an electron-hole plasma at the surface of the semiconductor substrate. The plasma in the transmission line acts as a moving short with a relativistic velocity, reflecting an incident microwave and up-shifting the frequency through the double Doppler effect. Power and energy conversion efficiencies have been theoretically analyzed for the frequency conversion. The results have shown that the converter can be used to produce short millimeter and submillimeter waves.
