Paper Abstract

A semiclassical approach is used to calculate the principle for heterodyne detection utilizing two optical detectors. These calculations show that excess-noise in the local-oscillator can be canceled and the balanced-detector optical heterodyne detection requires less local oscillator power compared with the traditional single-detector optical heterodyne detection. An experimental demonstration of excess-noise cancellation is reported.
