OPTOELECTRONIC DEVICE WITH ELECTRICALLY CONFIGURABLE METASURFACE FOR CONTROLLING LIGHT POLARIZATION AND ACHIEVING OPTICAL RESOLUTION BELOW CLASSIC DIFFRACTION LIMIT

摘要

The invention relates to an optoelectronic device with electrically-configurable metasurface for achieving optical resolution below the classic diffraction limit and for increasing the visibility, under difficult detection conditions, with applications in the field of optoelectronic couplers with surface plasmons and microscopy. According to the invention, the optoelectronic device is made by overlapping two cells with liquid crystal: a surface cell (1) containing a nematic liquid crystal phase, with functions of a linear polarizer with controlled rotation of the polarization plane and a superlens, and a volume cell (3), which constitutes a retarding plate with adjustable delay, containing a medium of cholesteric liquid crystal phase introduced between two glass plates (2, 4) coated with a layer of conductive oxide and a polymer, both transparent in visible and near infrared spectrum.
