The light control performance of photonic crystals is closely related to their lattice constant, which typically requires the lattice constant to be in the same order of magnitude as the working ...

Imagine shining two flashlight beams through each other — neither one blocks the other. However, some 3D computer models of laser systems depict the laser beam as a cylinder. Those models give the ...
