    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 camera system includes a first camera having a low-resolution image sensor with a plurality of image sensing regions. The camera system includes a plurality of high-resolution cameras. Each of the high-resolution cameras is associated with a set of the plurality of image sensing regions. The first camera is configured to detect motion based on sensed images, identify a set of the image sensing regions based on the motion, and power on the high-resolution camera associated with the identified set of image sensing regions.

    摘要： The optical switch operates in two stages. In the first stage, the bubble is “blown” into the trench. 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. Seperate side heaters are placed in thermal contact to the sidewalls. This results in a switch that is more stable, energy efficient, and has a longer mean time to failure.
