Mikaelyan, Andrey Leonovich

The brother of the famous physicist , academician of the Academy of Sciences of the Armenian SSR Mikhail Leonovich Ter-Mikaelyan ( 1923 - 2004 ).

• In 1949 he graduated from the Moscow Electrotechnical Institute of Communications (MEIS).
• In 1952 he defended the dissertation of a candidate of technical sciences.
• In 1956 he defended his thesis of Doctor of Technical Sciences.
• In 1957, he was awarded the title of Professor of MEIS.
• Since 1958, A. L. Mikaelyan served as head and scientific director of the laboratory (department) of laser technology, and then the Institute of Radio Optics as part of the Vega Radio Engineering Concern .
• On December 26, 1984, he was elected a corresponding member of the USSR Academy of Sciences in the Department of Informatics, Computer Engineering and Automation (element base, materials of computer technology and diagnostics).
• December 15, 1990, was elected an academician of the USSR Academy of Sciences in the Department of Informatics, Computer Engineering and Automation (automation, including scientific instrumentation).
• In 1991-2006 - Director of the Institute of Optical Neural Technologies of the Russian Academy of Sciences and its scientific adviser.
• Since November 2006 - Scientific Director of the Center for Optical Neural Technologies, NIISI RAS.

In addition, Mikaelyan was the head of the Department of Radio Optics at the Moscow Institute of Physics and Technology , and wrote (with two co-authors) the first in the USSR monograph on quantum generators, which taught many physicists who later worked in this field. He served as editor-in-chief of the international journal Optical Memory and Neural Networks, organized by him, and led the RAS Scientific Council on Optical Memory Problems. Under his scientific supervision more than 30 people defended their theses, among them 6 later became doctors of sciences ^[2] .

Mikaelian founded a number of new, widely used scientific fields in optoelectronics, microwave optics, holography. He developed the theory of magneto-optical phenomena in waveguides with ferrites . Based on it, he and his employees created a new class of microwave equipment, which are currently widely used ^[3] .

Mikaelian discovered the phenomenon of multiple focusing of electromagnetic waves and self-healing of the wave front in inhomogeneous media. He put forward the idea of ​​creating an optical waveguide based on this phenomenon. Such self-focusing optical fibers are currently used in communication systems, in various kinds of optical and medical devices ^[3] .

He developed a number of methods for solving inverse problems of geometric optics. The application of these methods allowed us to create a new class of channeling and focusing systems (in particular, Mikaelian lenses), which forms a separate direction of gradient optics ^[3] .

Mikaelian suggested using optical memory in computer technology. He belongs to the idea of ​​using holography for storing and processing large amounts of information. He and his colleagues proposed a method for optical realization of high-order neural models , showed their high efficiency for the recognition of noisy images , and developed a new class of holographic and optoelectronic devices ^[3] , in particular, electro-optical modulators based on lithium niobate crystals ^[2] .

Author of a number of significant and highly cited journal publications on gradient fibers and lenses, waveguide magnetooptics, single-mode lasers, optical memory problems, as well as monographs on solid-state lasers, holography and optical methods in computer science, microwave ferrites ^[3] .
