| 20120044970 | Temperature-Responsive Photonic Crystal Device - A temperature-responsive photonic crystal device comprising having a temperature-responsive photonic crystal material, whereby exposure of the device to a temperature above a predetermined threshold temperature is indicated by a detectable change in the device. | 02-23-2012 |
| 20110233476 | Tunable Photonic Crystal Composition - A tunable photonic crystal composition comprising: tunable photonic crystal particles having a polymer network with a periodic modulation of refractive indices, the polymer network having a reflectance wavelength, wherein the periodic modulation of refractive indices is responsive to an external stimulus and the reflectance wavelength is shifted in response to the external stimulus; and a carrier in which the particles are dispersed. | 09-29-2011 |
| 20110222142 | PHOTONIC CRYSTAL DEVICE - A photonic crystal device comprising: a photonic crystal material having an initial ordered structure and a viewing surface, the initial ordered structure giving rise to a first optical effect detectable from the viewing surface; and a removal layer removably attached with the viewing surface or an opposing surface of the photonic crystal material opposite to the viewing surface; wherein mechanical removal of at least a portion of the removal layer results in a structural change in at least a portion of the initial ordered structure of at least a portion of the photonic crystal material respective to the portion of the removed removal layer, thereby resulting in a changed portion different from the initial ordered structure, the changed portion giving rise to a second optical effect detectable from the viewing surface and detectably different from the first optical effect. | 09-15-2011 |
| 20110164308 | TUNABLE BRAGG STACK - A tunable photonic crystal device comprising: alternating layers of a first material and a second material, the alternating layers comprising a responsive material, the responsive material being responsive to an external stimulus, the alternating layers having a periodic difference in refractive indices giving rise to a first reflected wavelength; wherein, in response to the external stimulus, a change in the responsive material results in a reflected wavelength of the device shifting from the first reflected wavelength to a second reflected wavelength. | 07-07-2011 |
