Parametrical neural network based on the four-wave mixing process
We develop a formalism allowing us to describe operating of a network based on the parametrical four-wave mixing process that is well-known in nonlinear optics. It is shown that the storage capacity of such a network is higher compared with the Potts-glass neural networks. r 2003 Elsevier Science B.V. All rights reserved.
متن کاملUltrafast gating using a nonlinear Sagnac interferometer
Ultrafast gating is a powerful technique for applications such as time resolved spectroscopy [ 1-3 ], imaging through scattering media [4-7 ], or nonlinear optics [ 8 ]. Several methods have been used, each of which has its own limitations. The Kerr shutter [ 3 ] is extremely fast (femtosecond) but requires high peak power lasers. It has a maximum transmission of approximately 10 percent, and i...
متن کاملSagnac interferometer for gravitational-wave detection.
We have investigated a zero-area Sagnac interferometer as a broad band gravitational-wave detector. Frequency response measurements of a laboratory-scale interferometer are in excellent agreement with theory. The measured contrast ratio, 0.996, is insensitive to induced birefringence, laser-frequency variation, arm imbalance, and dc mirror displacement. A near shot-noise-limited phase sensitivi...
متن کاملSurface-enhanced nonlinear four-wave mixing.
We report on a particularly strong third-order nonlinear response from nanostructured gold surfaces. Two incident laser beams with frequencies omega{1} and omega{2} give rise to four-wave mixing (4WM) fields with frequencies 2omega{1}-omega{2} and 2omega{2}-omega{1}. We demonstrate that the nonlinear response can be purely evanescent and that nanostructured surfaces convert the evanescent energ...
متن کاملSingle-photon Sagnac interferometer
We present the first experimental demonstration of the optical Sagnac effect at the single-photon level. Using a high quality guided-wave heralded singlephoton source at 1550 nm and a fibre optics setup, we obtain an interference pattern with net visibilities up to (99.2 ± 0.4%). On the basis of this high visibility and the compactness of the setup, the interest of such a system for fibre optic...
