Abstract

We report on photonic frequency double-mixing conversion utilizing an InGaAs channel HEMT. A 1-GHz modulation signal on a 112.5-GHz carrier is electrically input to the gate, whereas a 1.58-μm dual wavelength CW laser beam having a frequency difference of 87.5-GHz local signal are irradiated to the channel. The InGaAs HEMT works as a photomixer generating a 87.5-GHz local signal which is then electrically mixed to the 5-GHz modulated 112.5-GHz carrier signal, resulting in the down-conversion of the 5-GHz signal to a 25-GHz intermediate frequency (IF) band.
