    摘要: A photonic device is provided having a two or three-dimensionally periodic structure of interconnected members with alterable spacing between the members. The structure is composed of a shape memory polymer configured to be thermo-mechanically tunable to display a plurality of optical properties under a series of temperature changes and stress. A method of producing a photonic device based on a shape memory polymer is provided. A mold, having a two or three-dimensionally periodic structure of interconnected components with a characteristic spacing between the components, is infiltrated with a shape memory polymer precursor to form a composite structure. The composite structure is solidified. The mold is removed from the composite structure to form a photonic device as an inverse replica of the mold.
