Detection of Weak Microwave Modulation of Light

Abstract

WE have devised a method of detecting very low levels of modulation on a laser beam, with the object of assessing the performance of microwave light modulators. The system may either be used simply to indicate the presence of modulation, or, in conjunction with a Fabry–Perot interferometer, to demonstrate the existence of optical sidebands as discrete frequencies.
