Phase-Only Optical Information Processing
نویسنده
چکیده
In order to perform an experiment into optical phase-only correlation it was necessary to fabricate an SLM to the highest standards possible. Chapter five has provided a background to the electronic operation of the 16×16 SLM and the liquid crystal light modulation mechanism used in this project. Actual fabrication of a working spatial light modulator is an extremely delicate process requiring a high degree of preparation and manual dexterity. One major difficulty in SLM fabrication is the accurate positioning of the glass cover cube over the VLSI backplane (referred to as the `chip' in what follows), so that the fragile chip bonding wires are not damaged. Further, the glass should ideally lie absolutely parallel to the chip surface so as not to introduce a wedge into the liquid crystal layer.

In this paper a method for digitally recording four quarter-reference-wave-holograms (by CCD) in a Mach-Zehnder interferometer setup, and reconstructing the object wave-front by numerical method is presented. The terms of direct transmission, auto-correlation and conjugate wave in the four wave reconstruction are cancelled out and only one original object wave is left after overlapping. Reconst...
متن کاملSpectral phase conjugation via extended phase matching
It is shown that the copropagating three-wave-mixing parametric process, with appropriate type-II extended phase matching and pumped with a short second-harmonic pulse, can perform spectral phase conjugation and parametric amplification, which shows a threshold behavior analogous to backward-wave oscillation. The process is also analyzed in the Heisenberg picture, which predicts a spontaneous p...

It is suggested that a quantum neural network (QNN), a type of artificial neural network, can be built using the principles of quantum information processing. The input and output qubits in the QNN can be implemented by optical modes with different polarization, the weights of the QNN can be implemented by optical beam splitters and phase shifters. Since it was first proposed by Feynman [1], th...

A great effort has recently gone into the search for practical architecture for quantum information processing systems. In this paper we focus on optical implementations of quantum information processing systems – in particular quantum phase gate[1]. One of the possible ways to realize this system requires strong interaction of the photonic qubits. Sufficiently strong interactions have been una...

متن کاملDelay Line Optical Recognizer Based On Coherent-To- Chaotic Light Conversion
We demonstrate a delay line optical recognizer at 2.5 Gbit/s. Recognition is based on a coherent-to-chaotic light conversion followed by a fiber array correlation filter. Experimental evidence shows performance improvement in comparison with a classical scheme as far as phase noise is concerned. An experimental characterization of the recognizer is reported. Methods for improving the recognitio...
