20100027956 | MULTIPHOTON CURING TO PROVIDE ENCAPSULATED OPTICAL ELEMENTS - Methods of fabricating optical elements that are encapsulated in monolithic matrices. The present invention is based, at least in one aspect, upon the concept of using multiphoton, multi-step photocuring to fabricate encapsulated optical element(s) within a body of a photopolymerizable composition. Imagewise, multiphoton polymerization techniques are used to form the optical element. The body surrounding the optical element is also photohardened by blanket irradiation and/or thermal curing to help form an encapsulating structure. In addition, the composition also incorporates one or more other, non-diffusing binder components that may be thermosetting or thermoplastic. The end result is an encapsulated structure with good hardness, durability, dimensional stability, resilience, and toughness. | 02-04-2010 |

20110156002 | LIGHT SOURCE HAVING LIGHT BLOCKING COMPONENTS - Light emitting systems are disclosed. The light emitting system includes an electroluminescent device that emits light at a first wavelength from a top surface of the electroluminescent device. The light emitting system further includes a construction proximate a side of the electroluminescent device for blocking light at the first wavelength that would otherwise exit the side. The light emitting system further includes a re-emitting semiconductor construction that includes a II-VI potential well. The re-emitting semiconductor construction receives the first wavelength light that exits the electroluminescent device and converts at least a portion of the received light to light of a second wavelength. The integrated emission intensity of all light at the second wavelength that exit the light emitting system is at least 4 times the integrated emission intensity of all light at the first wavelength that exit the light emitting system. | 06-30-2011 |
