DIGITAL FREQUENCY SHIFTER FOR 10.6 MICRON RADIATION.
Abstract
A theoretical and experimental study of frequency shifters for 10.6 microns is presented. Three different designs were considered. Two of these designs made use of the electro-optic effect in GaAs to obtain a single side band frequency shift. The third design utilized the acousto-optic properties of germanium. Bragg reflection and 60 percent conversion efficiency were obtained in this acoustic frequency shifter with an input power of 4.4 watts at 10 MHz. A design is presented for a digital frequency shifter which can produce discrete frequency shifts from -1.2 GHz to +1.2 GHz in 200 MHz steps. (Author)
