“…On the contrary, in the range of magnification values 3 6 M = − the difference between a sphere and a SIL becomes pronounced, as reported e.g. in [75,94,96,115,117,122,138,149,155,161]. This latter range of magnifications has been, probably, the most investigated in publications.…”

Materials with relatively small refractive indices (2 n <), such as glass, quartz, polymers, some ceramics, etc., are the basic materials in most optical components (lenses, optical fibres, etc.). In this review, we present some of the phenomena and possible applications arising from the interaction of light with particles with a refractive index less than 2. The vast majority of the physics involved can be described with the help of the exact, analytical solution of Maxwell's equations for spherical particles (so called Mie theory). We also discuss some other particle geometries (spheroidal, cubic, etc.) and different particle configurations (isolated or interacting) and draw an overview of the possible applications of such materials, in connection with field enhancement and super resolution nanoscopy.

“…Indeed, superresolution localization microscopy has already been utilized to characterize the local field enhancement of plasmonic nanostructures. Superresolution on single structures was achieved by isolating nanoprobes with temporal photoactivation [48] or using (slow) diffusion in an immersion liquid [49][50][51][52][53] and retrieving the positions of the nanoprobes by fitting snapshot fluorescent images with the point spread function (PSF). Such a photoactivation approach requires very particular fluorophores, while using diffusion assumes particular solvents that, in turn, limit the dielectric environment of the system being imaged.…”

Periodic plasmonic nanostructures have been found promising in controlling photoluminescence directivity and efficiency for a wide variety of applications. Because of the inhomogeneous spatial distribution of the photonic resonances of periodic plasmonic nanostructures, their influence on emission is strongly dependent on the position of emitters relative to the nanostructures. Therefore, mapping the local dependence of directivity, efficiency, and emission rate enhancements is key to understanding and optimizing the devices. We introduce a method of mapping the local enhancement of spontaneous emission rates of emitters coupled to periodic nanostructures based on stochastic superresolution imaging. As an example, we show superresolved measurements of the local density of states (LDOS) at 605 nm induced by a hexagonal lattice of aluminum nanoantennas with a spatial resolution of 40 nm, defined by the size of the colloidal nanosources we use as randomly dispersed probes. We demonstrate that our method is superior to near-field mapping of emission rates. Comparison with electrodynamic simulations indicates that the variation of the decay rate of the emitters in the investigated sample is hardly influenced by the lattice modes and mainly governed by single-particle LDOS variations and nearest-neighbor interactions.

“…Существует множество способов как уменьшить влияние этого ограничения (использование рентгеновских волн [2,3], иммерсионная микроскопия [4]), так и полностью его избежать (зондовая микроскопия [5][6][7]). Одним из способов преодоления дифракционного предела в оптике (получения сверхразрешения как в микроскопии, так и в литографии) является использование оптических суперосцилляций.…”

Оптические суперосцилляции являются одним из способов преодоления дифракционного предела. Явление суперосцилляций известно уже более полувека, но до сих пор существуют весьма ограниченный набор формы получаемых картин распределения света. Использование интерференции пучков Бесселя и Гаусса в настоящий момент является наиболее исследованным теоретически и фактически единственным методом получения оптических суперосцилляций на практике. В данной работе представлен новый метод получения оптических суперосцилляций, основанный на явлении трехволновой интерференции. Исследованы теоретические основы получения оптических суперосцилляций на основе рассмотрения распределения амплитуды поля при интерференции трёх когерентных коллимированных источников. Исследована зависимость контраста оптических суперосцилляций от соотношения амплитуд волн, которая имеет экспоненциальный вид. Также исследована зависимость размера оптических суперосцилляций от их контраста, которая, как оказалось, имеет степенную форму. Выполнено моделирование двумерных интерференционных картин оптических суперосцилляций, создаваемых тремя компланарными волнами. В этом случае оптические суперосцилляции имеют постоянный размер вдоль интерференционных полос. В случае некомпланарных волн при движении вдоль интерференционных полос наблюдается периодическое исчезновение и появление оптических суперосцилляций. Ключевые слова: оптические суперосцилляции; интерференция; субволновые эффекты.
