Strong resonant polarization conversion is observed in the
reflectivity properties of one-dimensional (1-D) lattices of air
trenches deeply etched in AlGaAs surface waveguides. The symmetry
properties and the magnitudes of the observed effects are found to be in
good agreement with the results of scattering matrix calculations

    • "The appearance of resonant reflection from waveguide inhomogeneities, such as particles, is analogous to resonant reflection from periodic gratings (Wood's anomalies) [9]. The guided-mode resonances offer opportunities to create mirrors and filters with resonant properties [10] [11] [12]. The formation of hybrid particle-waveguide state allows one to efficiently propel particles without intrinsic resonances, such as WGM resonances used in Ref. [13]. "

    ABSTRACT: Resonances can give rise to the appearance of large and highly frequency selective optical forces on microparticles. The forces are studied in two cases: when intrinsic resonances in dielectric particles exist and when resonances are created as a result of the interaction of particles with waveguides. The resonant forces can be used for high accuracy particle sorting and power-efficient particle manipulation.

    • "In the diffraction-limited microscopes, the resolution scales with λ. In the case of microsphere-assisted imaging, the possible factors responsible for super-resolution include surface plasmon resonances in metallic nanostructures [12], whispering-gallery modes in dielectric microspheres [13], photonic nanojets [14] [15], and folded photonic dispersions in periodic structures [16] [17]. It can be suggested that in some of these mechanisms the resolution should be resonantly dependent on λ. "

    ABSTRACT: Microsphere-assisted ultramicroscopy is a powerful, yet simple, technique to visualize nanometric-scale objects with visible light. In this method, dielectric microspheres are placed in contact with the nanoscale objects, so that the spheres experience object's optical near-fields. The mechanism of imaging is still debated in the literature; however it is likely to involve surface plasmon resonances in metallic nanostructured objects, whispering gallery modes in dielectric microspheres and other factors. In this work we extended this technique from visible to deep-UV range. It is shown that imaging of nanoplasmonic structures at the wavelength of 248 nm can be achieved with ∼ 55 – 60 nm resolution, far beyond the diffraction limit. These results could shed light on the mechanism of super-resolution imaging by microspheres and further advance this technology for practical applications.

    • "One of the most important developments was a proposal [3] of using high-index (n > 1.8) microspheres either immersed in a liquid [4] or embedded in elastomeric films [9] [10] [11]. Despite simplicity of this method illustrated in Fig. 1, the super-resolution mechanisms are still debated in the literature including photonic nanojets [12], folded plasmon-polariton dispersions in periodic structures [13] [14] [15], localized surface plasmon resonances in metallic nanostructures [16], and whispering gallery modes in microspheres or cylinders [17]. Photonic nanojets have been proposed as precision laser scalpels [18] [19] [20] [21] and for detector enhancement [22] [23]. "

    ABSTRACT: In 2011, super-resolution imaging by microspheres emerged as an extraordinary simple and broadband technique. The mechanism of imaging remains a mystery still today. The most likely candidates are the optical near fields, plasmonic resonances, photonic nanojets and whispering gallery modes. The critical problem in this area is the experimental definition of resolution which historically has been based on subjective criteria. In this work, we use the Houston resolution criterion and show that the image treatment techniques widely accepted in diffraction-limited optics can be extended in the super-resolution area, providing a phenomenological tool to determine the super-resolution values. Using this approach, we demonstrated imaging of Au and Al nanoplasmonic arrays by microspheres with the resolution ∼λ/7. We also demonstrated super-resolution imaging by microfibers with resolution of ∼λ/6 across the fiber and a millimetre-scale field-of-view along the fiber. Finally, we developed a technology of embedding high-index microspheres in PDMS films which can be translated along the sample to achieve a surface scanning functionality. Such thin films can become a standard component in super-resolution imaging of nanostructures and biological objects.
