Patent number: 8628985Abstract: Light emitting devices with improved light extraction efficiency are provided. The light emitting devices have a stack of layers including semiconductor layers comprising an active region. The stack is bonded to a transparent lens having a refractive index for light emitted by the active region preferably greater than about 1.5, more preferably greater than about 1.8. A method of bonding a transparent lens to a light emitting device having a stack of layers including semiconductor layers comprising an active region includes elevating a temperature of the lens and the stack and applying a pressure to press the lens and the stack together. Bonding a high refractive index lens to a light emitting device improves the light extraction efficiency of the light emitting device by reducing loss due to total internal reflection. Advantageously, this improvement can be achieved without the use of an encapsulant.Type: GrantFiled: October 4, 2011Date of Patent: January 14, 2014Assignee: Philips Lumileds Lighting Company LLCInventors: Michael D.

Patent number: 6904192Abstract: An optical switch having liquid or bubbles in switching sites operates with a fluid pressure less than the vapor pressure of the liquid. This pressure differential is equal to the surface tension induced pressure drop across a bubble having a critical size selected according to switching site geometry. Each switching site has a stable state including a bubble larger than the critical size and another stable state with no bubble. Local heating provides nucleation energy to create a bubble but is not required to maintain the bubble. Globally or locally increasing the fluid pressure collapses bubbles in switching sites to reset all or selected switching sites. One switching site creates rapidly expanding bubbles near but outside the optical cavity of the switching site. The bubble's expansion causes liquid flow that locally increases pressure and collapses a bubble in the optical cavity or pushes the bubble from the optical cavity into an absorber cavity.Type: GrantFiled: October 7, 2002Date of Patent: June 7, 2005Assignee: Agilent Technologies, IncInventors: Dale W.

Publication number: 20040076363Abstract: The optical switch operates in two stages. In the first stage, the bubble is “blown” into the trench by either sidewall heaters or a dedicated central heater. In the second stage, the sidewalls are heated to achieve a dry wall condition by improving the thermal transfer path from the heat source to the reflecting wall. The sidewall heaters are positioned such that there is an indirect thermal path to the sidewalls of the trench. This results in a switch that is more stable, energy efficient, and has a longer mean time to failure.Type: ApplicationFiled: October 16, 2002Publication date: April 22, 2004Inventors: Dale W.
