Photochemically and Thermally Tunable Planar Defects in Colloidal Photonic Crystals

摘要

Photonic crystals (PCs) have attracted increasing attention as potential optoelectronic components for applications ranging from telecommunications to sensing,displays,lasing,and optical computing.They are characterized by a periodic dielectric structure leading to photonic band gaps or stop bands with a depleted photonic density of states.At specific wavelength ranges,the propagation of electromagnetic radiation can be suppressed along certain lattice directions.
