Abstract

Possible application of the GaN/AlN/SiC/GaN-structures for manufacturing of active optical elements designed for operation in extreme conditions and, in particular, for investigation of oceanic hydrothermal sources (the "black smokers") is considered in the research. Advances in epitaxial III-nitride technologies in terms of obtaining "thick" AlN-layers and multilayer heterostructures make it possible to formulate a new approach to creating electrically controlled lenses, in which the longitudinal piezo effect (in the direction of the optical axis) is assumed to be implemented. In contrast to the radial-oriented transverse piezo effect previously applied by scientists in order to create bending deformations in bimorph membrane-type microlenses, the proposed design uses thin transparent conducting GaN-layers as control electrodes. As a part of the stated concept, an algorithm is also developed, and simulations are performed in order to study changes in the magnitude and nature of the curvature of the outer GaN surface, depending both on changes in temperature and changes in control voltage. It is assumed that this design solution of the lens will allow for adaptive thermal compensation of its optical parameters with a possible change of ambient temperature in a wide range (up to 1000 ºC).
