a, Dielectric perturbations are located at the “peaks” or “valleys” in the transverse mode profile of high-order mode to maximize the mode overlap integral. b, Schematic view of the metamaterial ...

Interferometers, devices that can modulate aspects of light, play the important role of modulating and switching light signals in fiber-optic communications networks and are frequently used for gas ...

(Nanowerk Spotlight) The simplest way to trap light, or in general electromagnetic waves, in a finite region is to realize a region surrounded by mirrors so that light is not able to escape. The ...
