Abstract

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.

Claims (28)

1. A system for generating copies of a signal, comprising:

a first radiation source configured for providing a plurality of pump radiation beams, the plurality of pump radiation beams comprising more than two 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 the second-order nonlinear optical medium to generate, by performing three-wave mixing using a process of different frequency generation, a plurality of idlers, the plurality of idlers comprising more than two idlers, wherein the plurality of idlers comprise low-noise copies of the signal, wherein noise figures of the plurality of idlers are equivalent, and wherein the noise figures remain constant, independent of the number of idlers, such that each subsequently generated idler of the plurality of idlers does not degenerate quality of the plurality of idlers by impacting the noise figures, and wherein the noise figures in a high gain regime are 3 dB.

2. The system of claim 1 , wherein the first radiation source comprises an optical frequency comb.

3. The system of claim 1 , wherein the plurality of pump radiation beams is equal to the plurality of idlers.

4. The system of claim 1 , wherein the first radiation source comprises at least two individual lasers.

5. The system of claim 1 , wherein the plurality of idlers comprise amplified copies of the signal radiation beam, wherein the plurality of idlers are correlated and phase-dependent.

6. The system of claim 1 , further comprising:

an optical preprocessing device to receive the plurality of idlers.

7. The system of claim 6 , wherein the optical pre-processing device utilizes a portion of the plurality of idlers in one of: analog-to-digital conversion, or channelization of radio-frequency signals.

8. A method of generating copies of a signal, comprising:

obtaining, by a second-order nonlinear optical medium, a plurality of pump radiation beams from a first radiation source, the plurality of pump radiation beams comprising more than two pump radiation beams;

obtaining, by the second-order nonlinear optical medium, a signal radiation beam from a second radiation source; and

generating, by the second-order nonlinear optical medium, by performing three-wave mixing using a process of different frequency generation, a plurality of idlers, the plurality of idlers comprising more than two idlers, wherein the plurality of idlers comprise low-noise copies of the signal, wherein noise figures of the plurality of idlers are equivalent, and wherein the noise figures remain constant, independent of the number of idlers, such that each subsequently generated idler of the plurality of idlers does not degenerate quality of the plurality of idlers by impacting the noise figures, and wherein the noise figures in a high gain regime are 3 dB.

9. The method of claim 8 , wherein the first radiation source comprises an optical frequency comb.

10. The method of claim 8 , wherein the plurality of pump radiation beams is equal to the plurality of idlers.

12. The method of claim 8 , wherein the plurality of idlers comprise amplified copies of the signal radiation beam, wherein the plurality of idlers are correlated and phase-dependent.

13. The method of claim 8 , further comprising:

providing, by the second-order non-linear medium, to an optical preprocessing device, the plurality of idlers.

14. The method of claim 13 , wherein the optical pre-processing device utilizes a portion of the plurality of idlers in one of: analog-to-digital conversion, or channelization of radio-frequency signals.

15. A method of assembling a system for generating copies of a signal, comprising:

positioning a first radiation source configured for providing a plurality of pump radiation beams to provide the plurality of pump radiation beams to a second-order nonlinear optical medium, wherein the plurality of pump radiation beams comprise more than two pump radiation beams, and wherein the plurality of pump radiation beams enter the second-order nonlinear optical medium from a first direction;

positioning a second radiation source configured for providing a signal radiation beam to provide the signal to the second-order nonlinear optical medium, wherein the plurality of pump radiation beams enter the second-order nonlinear optical medium from the first direction; and

positioning the 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 generate, by performing three-wave mixing using a process of different frequency generation, a plurality of idlers in a second direction, the plurality of idlers comprising more than two idlers, wherein the plurality of idlers comprise low-noise copies of the signal wherein noise figures of the plurality of idlers are equivalent, and wherein the noise figures remain constant, independent of the number of idlers, such that each subsequently generated idler of the plurality of idlers does not degenerate quality of the plurality of idlers by impacting the noise figures, and wherein the noise figures in a high gain regime are 3 dB.
