Shin-Hyun Kim, Hyerim Hwang, and Seung-Man Yang, "Fabrication of Robust Optical Fibers by Controlling Tsunami-Driven Film Drainage of Colloids in Capillaries," Angewandte Chemie International Edition, Accepted for publication (2012)

Photonic crystal fibers have been created using spontaneous crystallization of colloidal particles in photocuable resin coated on inner wall of microcapillaries. Spontaneous crystallization and fast consolidation of the structures yield robust photonic crystals and the controlled deposition of films on the microcapillaries permits manipulation of the thickness and number of layers in the photonic crystal fibers. We demonstrated that a stop band in a colloidal photonic crystal fiber can enhance the efficiency of light guidance in off-TIR regime.
