Abstract

A composite photonic crystal comprising an inverse opal structure defining an ordered array of voids with a filler composition received within the voids. A property of the filler composition changes in response to a stimulus, such as a temperature change, thereby changing the band gap of radiation that is reflected by the composite photonic crystal.
