Abstract : The observation and quantitative measurement of optical heterodyne detection in the far infrared (Lambda = 118.6 micrometers) using a Ge:Ga detector are reported. The experimental results fall below theoretical predictions; the discrepancy is explained in terms of the NEP of the detector used and the low value of local oscillator power available in the experiments.
