Canonical and Poynting currents in propagation and diffraction of structured light: tutorial
Bohnishikha Ghosh, Anat Daniel, Bernard Gorzkowski +3
Local propagation and energy flux in structured optical fields is often associated with the Poynting vector. However, the local phase gradient (i.e., local wavevector) in monochrom…
Azimuthal backflow in light carrying orbital angular momentum
Bohnishikha Ghosh, Anat Daniel, Bernard Gorzkowski +1
M.V. Berry's work [J. Phys. A: Math. Theor. 43, 415302 (2010)] highlighted the correspondence between backflow in quantum mechanics and superoscillations in waves. Superoscillation…
Demonstrating backflow in classical two beams' interference
Anat Daniel, Bohnishikha Ghosh, Bernard Gorzkowski +1
The well-known interference pattern of bright and dark fringes was first observed for light beams back in 1801 by Thomas Young. The maximum visibility fringes occur when the irradi…
Noninvasive linear fluorescence imaging through scattering media via wavefront shaping
Anat Daniel, Dan Oron, Yaron Silberberg
We demonstrate focusing and imaging through a scattering medium noninvasively by using wavefront shaping. Our concept is based on utilizing the spatial fluorescence contrast which…
Focusing light by wavefront shaping through disorder and nonlinearity
Hadas Frostig, Eran Small, Anat Daniel +3
Wavefront shaping is a powerful technique that can be used to focus light through scattering media, which can be important for imaging through scattering samples such as tissue. Th…
