Suppressing Material Loss for Functional Nanophotonics Using Bandgap Engineering
Mingsong Wang, Alex Krasnok, Sergey Lepeshov +6
All-dielectric nanoantennas have recently opened exciting opportunities for functional nanophotonics, owing to their strong optical resonances along with low material loss in the n…
Active Nanophotonics
Alex Krasnok, Andrea Alù
Recent progress in nanofabrication has led to tremendous technological developments in nanophotonics, which rely on the interaction of light with nanostructured matter. Nanophotoni…
Virtual Parity-Time Symmetry
Huanan Li, Ahmed Mekawy, Alex Krasnok +1
Parity-time (PT) symmetry has been opening exciting opportunities in optics, yet the required careful balance of loss and gain has been hindering its practical implementations. Her…
Virtual Optical Pulling Force
Sergey Lepeshov, Alex Krasnok
The tremendous progress in light scattering engineering made it feasible to develop optical tweezers allowing capture, hold, and controllable displacement of submicronsize particle…
Superradiation, Superdirectivity and Efficiency Boosting in Coherently Driven Antennas
Jian Wen Choong, Alex Krasnok
Antennas, i.e., elements transforming localized or waveguide modes into freely propagating fields and vice versa, are vital components for wireless technologies across the entire s…
Coherently Assisted Wireless Power Transfer Through Barely Transparent Barriers
Alex Krasnok
Wireless power transfer (WPT) technologies are becoming ubiquitous, but unlike wire technologies, they do not allow efficient energy transfer through barely transparent barriers. T…
