Here, we provide an overview of broadband cosite interference reduction using an optical system to perform incoherent counter-phase modulation and subtraction. The equation governing interference cancellation depth is derived and discussed with respect to two key parameters, attenuation and delay accuracy. Cancellation depth is then examined with respect to signal bandwidth and device parameters to provide a context for predicted cancellation performance. Experimentally recorded interference cancellation data is presented along with predicted performance to show the agreement of theory and data.
