Abstract
A self-assembled photonic crystal is formed using a template made by nanoimprint lithography. A layer of imprintable material is deposited on a substrate, a pattern is imprinted in the imprintable material to form a template (the pattern of the template being adapted to substantially constrain colloidal particles to a predetermined lattice), and colloidal particles are introduced onto the template, substantially filling the predetermined lattice.
