Abstract

A method for optical data processing, based on the mode of multipulse excitation of photon echo signals, has been proposed and applied to solution of the knapsack problem. In this case, along with the recognition of solvability, the solution itself is found in the optical processor. A scheme of a possible optical echo processor on molecular iodine vapor is presented.

Multipulse excitation of photon echo and principles of parallel functioning of optical echo-processors

Ivan I. Popov, M. Yu. Kokurin, Vera T. Nigmatullina

The phenomenon of multipulse photon echo in two-level quantum systems is used to construct a conceptual sketch of a device which involves two optical coprocessors operating in parallel. The device is designed for accelerated solution of NP-hard problems of discrete analysis. As an example, the application of coprocessors to the trinomial knapsack problem is considered in detail. The coprocessors work with sequences of exciting laser pulses of different amplitude-time forms and polarizations.

A physical principle of the design of two parallel coprocessors for solving the knapsack problem was proposed. These coprocessors operate on the basis of polarization properties of multipulse excitation and recording of the photon echo signals. The exciting pulse area is optimized to improve the resolution in solving combinatory problems.

Principles of construction of optical echo processors

An analysis is made of the possibility of utilization of the photon echo effect in optical digital processing of discrete images by the method of control operators, which makes it possible to solve a number of problems. Different regimes for the excitation of the photon echo are in practice usable in all component parts of a processor, which makes this effect potentially promising for the use in optical data processing.

Properties and parameters of the photon echoes (PEs) used in optical data processing are analyzed. Physical methods for constructing functional processors and measuring devices on the basis of PE are proposed. Experiments on detecting femtosecond PEs in inorganic nanofilms at the room temperature are described.
