Abstract
First and second tandemly positioned electrically biased semiconductor members radiate microwave energy in response to the receipt of an excitation light beam having two wavelengths related to the bandgaps of the members. The projected microwave beam may be made more narrow and directional if two of the members are electrically biased at the same time. An inefficient frequency doubler generates the two wavelength beam enabling a single light beam to excite both members in a simple, rugged photoconductive antenna element.
