(Nanowerk News) 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 ...

However, achieving three-dimensional confinement of light in a way that allows for precise control and manipulation has remained a challenging frontier. Previous attempts have often been limited to ...

Photonic space-time crystals are materials that could increase the performance and efficiency of wireless communication or laser technologies. They feature a periodic arrangement of special materials ...

a, Generation and tight focusing of femtosecond laser multi-beam optical field. b, Subwavelength photonic crystal structure fabrication and grating device preparation Credit must be given to the ...

Two University of Toronto physicists have spiralled a new twist out of the old subject of optics by creating a blueprint for a photonic crystal that paves the way for better, faster and perhaps ...
