Abstract

A broad and fast wavelength tuning of the photonic bandgap of a hybrid photonic band structure (PBS) formed from an achiral nematic liquid crystal and a polymer template. Remarkably, red-green-blue reflection from a single device and a single achiral nematic liquid crystal mixture is reported without any additional optical components such as a color filter.
