Super-resolution Fluorescence Microscopy

12.3K
Super-resolution fluorescence microscopy (SRFM) provides a better resolution than conventional fluorescence microscopy by reducing the point spread function (PSF). PSF is the light intensity distribution from a point that causes it to appear blurred. Due to PSF, each fluorescing point appears bigger than its actual size, and it is the PSF interference of nearby fluorophores that causes the blurred image. Various approaches to achieving higher resolution through SRFM have recently been...

Imperfections in Crystal Structure: Point, Line and Plane Defects

150
A perfect crystal, in theory, has a uniform structure with the same unit cell and lattice points throughout. However, any deviation from this periodic arrangement is known as an imperfection or defect. These defects can be categorized into three types: point, line, and plane defects.Point defects occur when there is a deviation from the ideal due to missing atoms, displaced atoms, or additional atoms. These imperfections might occur due to imperfect packing during crystallization or because of...

    Main Methods:

    • Fabrication of a multilayer dielectric structure comprising absorbing and non-absorbing materials.
    • Optical characterization to verify unidirectional reflectionless light transport.
    • Theoretical analysis and experimental measurement of phase transitions around the EP.

    Main Results:

    • Successful implementation of a 4-inch optical exceptional point structure.
    • Demonstration of wafer-scale unidirectional reflectionless light transport.
