A system and method for generating copies of a signal includes a first radiation source configured for providing a plurality of pump radiation beams, a second radiation source configured for providing a signal radiation beam, and a second-order nonlinear optical medium to receive the plurality of pump radiation beams from the first radiation source and the signal radiation beam from the second radiation source and to emit a plurality of idlers, where the plurality of idlers are low-noise copies of the signal.

Generation of multiple low-noise copies of optical signals

Devices and methods for converting an input electromagnetic signal to an output optical signal consisting of dual sidebands with equalized quantum-limited noise figures of about 3 dB are provided. For instance, a device includes an input for receiving the input electromagnetic signal and an output for delivering the output optical signal; and a non-linear material component connected between the input and the output of the device, the non-linear material component having a non-linear electric susceptibility, wherein the non-linear electric susceptibility of the non-linear material component is selected to mix the input signal with an optical pump signal to produce the output optical signal, wherein the output optical signal has sidebands corresponding to the input signal, and amplifying this optical signal in a phase-sensitive amplifier to produce an output optical signal with sidebands having equalized amplitudes and noise figures.
