Patent number: 8362684Abstract: A light-emitting device comprising a population of quantum dots (QDs) embedded in a host matrix and a primary light source which causes the QDs to emit secondary light and a method of making such a device. The size distribution of the QDs is chosen to allow light of a particular color to be emitted therefrom. The light emitted from the device may be of either a pure (monochromatic) color, or a mixed (polychromatic) color, and may consist solely of light emitted from the QDs themselves, or of a mixture of light emitted from the QDs and light emitted from the primary source. The QDs desirably are composed of an undoped semiconductor such as CdSe, and may optionally be overcoated to increase photoluminescence.Type: GrantFiled: May 7, 2012Date of Patent: January 29, 2013Assignee: Massachusetts Institute of TechnologyInventors: Moungi G. Bawendi, Jason Heine, Klavs F. Jensen, Jeffrey N. Miller, Ronald L. Moon

Patent number: 7679818Abstract: The present invention provides an optical switch including a loss element having a signal loss, and a rare earth doped gain element optically connected in series with the loss element. The rare earth doped gain element is operable to produce a signal gain. The signal gain and the signal loss are about equal. The present invention also provides a method of optical switching including optically connecting a loss element in series with a rare earth doped gain element and passing an optical signal through the loss element and the gain element. The loss element attenuates the optical signal by a first amount. The method further includes selectively applying an optical pump to the gain element to perform the switching, the gain element amplifying the optical signal by the first amount in response to the optical pump.Type: GrantFiled: January 3, 2008Date of Patent: March 16, 2010Assignee: Avago Technologies Fiber IP (Singapore) Pte.
