  • Phase-change materials and optical limiting devices utilizing phase-change materials
    Patent number: 8259381
    Abstract: An optical limiting structure includes a metal layer with a single metal particle or a plurality of metal particles spaced from each other so as to form an array, where the metal particles have sizes no greater than about 1000 nanometers. A phase-change material layer is disposed adjacent at least a portion of the metal layer, where the phase-change material layer includes a phase-change material. The optical limiting structure is configured to transition from a first optical state to a second optical state, where the optical limiting structure substantially limits transmittance of light of at least one wavelength through the optical limiting structure at the second optical state, and the at least one wavelength at which the optical limiting structure substantially limits transmittance of light is different from any wavelength of light at which transmittance is substantially limited through the phase-change material prior to integration into the optical limiting structure.
