Abstract

Until recently the direct measurement of frequencies in the infra-red spectral region has not been possible because of the lack of suitable detectors and mixers with response times of the order of 10−13 to 10−14 seconds. Through the development over the last three or four years of the metal-oxide-metal diode and Josephson junction point contact devices such measurements are now feasible.
