摘要： 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 optical element 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 optical element (e.g., a lens or an optical concentrator) to a light emitting device comprising an active region includes elevating a temperature of the optical element and the stack and applying a pressure to press the optical element and the light emitting device together. A block of optical element material may be bonded to the light emitting device and then shaped into an optical element. Bonding a high refractive index optical element 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.

摘要： 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.

摘要： Vertical cavity surface emitting laser systems and methods of making the same are described. In one aspect, a vertical cavity surface emitting laser system has a bottom side that may be flip-chip mounted to a driver substrate and a top side that is configured to transmit light through an optically transparent substrate. By this configuration, vertical cavity surface emitting laser systems may be packed together with a greater density and operated at greater speeds relative to, for example, wire bonded vertical cavity surface emitting laser systems. In addition, such systems may be flexibly tailored to produce light over a wide range of wavelengths. Such systems also may be efficiently packaged on a wafer scale.

摘要： A bubble optical switch includes a switching chamber, a static bubble drum, and a quenching pipe. The static bubble drum is adapted to contain a static bubble. In the inactive state, the static bubble remains within the static bubble drum and the switching chamber is filled with index matching fluid. To activate the switch, heat is introduced expanding the static bubble into the switching chamber displacing the index matching fluid with vapor. Then, the optical signal is reflected from the wall of the switching chamber. When the heat is removed, the static bubble contracts back into the static bubble drum. Because the temperature required to expand the static bubble is lower than the temperature required to nucleate a bubble from the fluid, the reliability and lifetime of the switch is increased. Further, due to the properties of the contracting static bubble, no residual bubble forms, thereby alleviating problems associated with residual bubbles of the prior art bubble switches.
摘要翻译：气泡光学开关包括开关室，静止气泡鼓和淬火管。静态泡沫桶适于容纳静态气泡。在非活动状态下，静态气泡保持在静态气泡鼓内，并且开关室填充有折射率匹配流体。为了激活开关，引入热量，将静态气泡膨胀到开关室中，以使蒸汽与折射率匹配的液体移动。然后，光信号从开关室的壁反射。当除去热量时，静态气泡回到静止气泡鼓中。由于膨胀静态气泡所需的温度低于从流体中形成气泡所需的温度，所以开关的可靠性和寿命增加。此外，由于收缩静止气泡的特性，不会形成残余气泡，从而减轻与现有技术的气泡开关的残留气泡相关的问题。
