SYSTEM AND METHOD FOR OPTICAL SIGNAL QUADRATURE SEPARATION

摘要

A system and method for separating signal quadratures includes obtaining, by a parametric amplifier, an input signal, amplifying, by the parametric amplifier, the input signal to create an amplified signal and generating an idler. The idler is a conjugate image of the input signal. The system and method also include obtaining, by a frequency converter, the amplified signal and the conjugate image and converting the amplified signal and the conjugate image into a first output and a second output, where the first output includes a first signal quadrature and the second output includes a second output quadrature.
