Mialkivska I. High-speed specialized optoelectronic semiconductor modulators-based computers

The work purpose is increase of speed of specialised computers at the expense of use of parallel input-output and parallel processing of the information presented in a matrix kind. Object of research is parallel processing of files of the information of the big dimension in specialised computers with parallel input-output. Objects of research are specialized optoelectronic semiconductor modulators-based computers with parallel input-output for parallel performance of digit-by-digit logic operations over big dimensional files. For the decision of tasks in view in dissertational work the methods of researches based on use of the system analysis, mathematical modeling, the theory of estimation of efficiency and optimization, the theory of chains, signals and systems, methods of the analysis and synthesis of electronic schemes are used. Novelty of the received results consists in the offered method of two-wave management optoelectronic semiconductor modulator on the basis of nonlinear dependence of a spectrum of absorption of information signals which pass through a modulator, from a spectrum of an optical signal of management that has allowed to exercise administration of passage of information radiation with different lengths of waves; for the first time the received analytical model for absorption research electroabsorption the modulator on the basis of semiconductor GaAs/AlGaAs with quantum wells from the enclosed pressure, based on experimental data that allows to predict absorption factor for optically controlled electroabsorption the modulator on the basis of the double-diode; to the offered architecture multilayered optoelectronic modulator on a basis electroabsorption modulators with two-wave management for performance of a set of logic operations over matrixes that allows to raise speed at the expense of occurrence of signals with greater in time density. Practical results consist in working out of schemes of logic elements AND,NAND, NOT, the sum on the module 2 on optically controlled electroabsorption modulators; in construction of schemes of specialized computers for performance of operations element-to-element multiplication and addition of two matrixes 10240х10240 elements on a basis optoelectronic semiconductor modulators; in creation of modeling programs of performance of logic operations on the basis of multilayered optoelectronic modulator with evident display of results. Introduction degree: results of dissertational work it is introduced at creation of the automated information retrieval system which is used at the Vinnytsia Commodity Universal Stock Exchange, and also in educational process on chair Laser and Optoelectronic Technicians of Vinnitsa National Technical University. Area (branch) of use: in computer facilities at processing of big dimensional data files.
