We experimentally demonstrate a very large dynamic optical reflection modulation from a simple unpatterned layered stack of phase-change materials ultrathin films. Specifically, we theoretically and experimentally demonstrate that properly designed deeply sub-wavelength GeSbTe (GST) films on a metallic mirror produce a dynamic modulation of...

Multi-dielectric coated coverslip can be designed to reach large optical field enhancements when working under proper illumination conditions and in total internal reflection. In an objective-based total internal reflection fluorescence microscopy (TIRF-M), we propose to use the resulting large field enhancement supported in such coverslip to...

With the rapid progress in the field of metasurfaces and their use in miniature integrated devices arise the quest for cheap mass production of efficient metasurfaces. We suggest a novel way to design and fabricate phase-gradient Huygens metasurfaces using laser-annealing of uniform particles made of As2S3 chalcogenide glass. We show that a...

We experimentally demonstrate a very large dynamic optical reflection modulation from a simple unpatterned layered stack of phasechange materials ultrathin films.

In this paper, we discussed how multi-dielectric coated coverslip can be designed to reach large optical field enhancement when working under proper illumination conditions and in total internal reflection. As objectivebased total internal reflection fluorescence microscopy (TIRF-M) is also based on total internal reflection illumination, we...
