Trapping light with a twister

Plot of radiative quality factor as a function of wave vector for a photonic crystal slab. At five positions, this factor diverges to infinity, corresponding to special solutions of Maxwell equations called bound states in the continuum. These states have enough energy to escape to infinity but remain spatially localized. Courtesy of the researchers

New understanding of how to halt photons could lead to miniature particle accelerators, improved data transmission. << more >>
