Self-Assembling Photonic Crystals Miniaturize Optical Components and Enhance Laser Efficiency

Colloidal particles that are used in a wide array of technical applications, such as cosmetics, inks, paints, and foods, have the ability to self-assemble into an exceptional range of crystalline structures that are densely packed.

For many years, scientists have been working to coax colloidal spheres so that they self-assemble into more thinly distributed lattices to allow the release of potentially valuable optical characteristics. Such structures are known as photonic crystals and have the ability to miniaturize optical components, enhance the efficiency of lasers, and greatly increase the ability of engineers to control the light flow, by a great degree.
