“Our colloidal films have many defects,” he says ... one major advantage of creating displays out of tunable photonic crystals such as these is that you potentially get a threefold increase ...

WGM cavities are used in sensing, nonlinear optics, and cavity optomechanics. Photonic crystal cavities are created by introducing defects in periodic dielectric structures known as photonic crystals.

Recent work has focused on the development and fabrication of magnetic photonic crystals ... we have also studied ion implantation-induced defect generation in single-crystal oxides. This work has led ...

At the same time, light (in a form of focused laser beams) can be used to control these materials by shaping patterns of molecular orientations, optical trapping of colloidal particles and defects ...
