Abstract
A photonic crystal device including a photonic crystal material and an activation surface. The photonic crystal material exhibits a first reflectance spectrum in an unactivated state, and, in response to mechanical stimulation, exhibits a second reflectance spectrum in an activated state. Application of a force at an activation portion of the activation surface offset from a material-supporting portion of the activation surface causes a deformation of the photonic crystal material sufficient to bring the photonic crystal material to the activated state.
Claims21
A photonic crystal device comprising:
- a photonic crystal material exhibiting a first reflectance spectrum in an unactivated state, the photonic crystal material having an activated state in response to at least mechanical stimulation and exhibiting a second reflectance spectrum different from the first reflectance spectrum in the activated state;
- an activation surface having a material-supporting portion directly coupled to at least a portion of the photonic crystal material;
- and
- an activation portion defined on the activation surface offset from the material-supporting portion;
- wherein application of a force at the activation portion causes a deformation of the photonic crystal material sufficient to bring the photonic crystal material to the activated state.
