Patent application number | Description | Published |
20090219622 | Light-absorbing structure and methods of making - A critically coupled optical resonator absorbs greater than 95% of incident light of the critical wavelength with an absorber layer less than 10 run thick. | 09-03-2009 |
20100014799 | Optical structures including nanocrystals - An optical structure can include a nanocrystal on a surface of an optical waveguide in a manner to couple the nanocrystal to the optical field of light propagating through the optical waveguide to generate an emission from the nanocrystal. | 01-21-2010 |
20100051967 | Absorbing film - Materials can be prepared in a layer-by-layer fashion on a patterned first substrate and subsequently transferred to a second substrate. The transfer step can preserve the pattern of the first substrate, such that the second substrate will bear a pattern of the transferred material. The material can be an electrostatic multilayer including a light absorbing dye, such as a J-aggregating cyanine dye. | 03-04-2010 |
20110057125 | LIGHT EMITTING MATERIAL - A composition can include a first moiety capable of being excited to an excited state, and a second moiety capable of accepting excited state energy from the first moiety. The second moiety is capable of emitting light with a FWHM of 15 nm or less when excited. The second moiety can be a J-aggregate and the rust moiety can be a semiconductor nanocrystal. | 03-10-2011 |
20120327052 | LED ARRAY WITH PHOTODETECTOR - Embodiments of the present invention provide for an array, and corresponding method of forming an array, that includes a plurality of light emitting devices. The light emitting devices are disposed over a substrate, and a photodetector detects light emitted through the substrate from the light emitting devices. Further, a substantially constant brightness may be maintained in a plurality of light emitting devices disposed over the upper surface of a substrate in an array. Light emitted through the substrate from each of the light emitting devices is measured, and the voltage level applied to each of the light emitting devices is varied to maintain a substantially constant brightness level of light emitted from the light emitting devices. | 12-27-2012 |
