Abstract
Photonic crystals(PCs) are periodic dielectric-structure materials with a photonic bandgap for electromagnetic waves.By combining stimuli-sensitive material with photonic crystals,the formed photonic crystals can respond to the external environments,which are named as responsive photonic crystals.According to different external stimuli,responsive photonic crystals can be classified into three different types: chemical responsive photonic crystals,physical responsive photonic crystals and biological responsive photonic crystals.we reviewed the progress in physical responsive photonic crystals in recent years,including temperature-responsive,solvent-responsive,electric filed-responsive,magnetic filed-responsive and mechanical force-responsive photonic crystals.
