Princeton Docket #08-2453
Researchers at Princeton University have developed a new process of filtering and enhancing signals from a noisy background, based on the non-linear interaction between coherent and incoherent waves. Princeton is currently seeking industrial collaborators to commercialize this technology.
The new process is an all-optical method of amplifying low-level signals and also provides a novel method for hiding information and recovering it. It works for both spatial and temporal pulses. Its novel feature is that it can improve signals over the propagation distance, as the signal can self-filter and self-amplify, at the expense of the surrounding noise.
It is anticipated that this technology will be extremely useful in signal processing, for amplification and filtering, for example, in night-vision amplifiers. The method can also be used in data security, where a low-level signal can be hidden in a background of noise, as for example in steganography and security stamping of DVDs.
Patent protection is pending.
