Abstract: Methods and systems for improved optical efficiency and brightness of display systems are provided herein. Embodiments use laser light sources in substantially continuous mode, thereby increasing the maximum overall output of an optical system. Embodiments exploit the small étendue of laser sources to lower the loss of throughput of an optical system. Embodiments enable a scrolling color scheme that allows a display system to be illuminated with two or more colors at any given time, thereby increasing the brightness of the display system. Embodiments can be used with liquid crystal displays and/or digital mirror displays. Embodiments can be used in single-panel and/or two-panel display systems.

Abstract: An optical apparatus can include an optical port array having an M×N array of fiber collimator ports. The array of ports is configured such that there is a gap within each column of ports located between two rows of ports. The gap is wide enough to permit a hitless beam switching trajectory to pass between the two rows of ports from one side of the array of ports to an opposite side.

Abstract: A switching element defines a transmitting state and a reflecting state for a pair of intersecting waveguides that have a gap at their intersection. In the preferred embodiment, the switching element exhibits total internal reflection at the gap sidewall from one waveguide to the other when not in the transmitting state. In the transmitting state, index-matching liquid fills the gap, enabling light to continue in the original waveguide direction. The switching element may use ink jet techniques or bubble techniques to displace index-matching liquid. The index-matching fluid may be projected from a gap between the waveguides by a jet mechanism, or a vapor or dissolved gas bubble may be formed to fill the gap between the waveguides to provide the reflecting state for the switching element. Using either of the techniques, heaters are employed to initiate the switching operation. In some embodiments, more than one heater is utilized. In the preferred embodiment, waveguides are formed on one substrate and heaters are formed on another. Then the substrates are aligned and bonded together to position the heaters in very close proximity to the intersection between the waveguides. Preferably, the switching element is one element in a matrix of such elements for routing signals between arrays of input and output waveguides.

Abstract: A new MSM photodetector, including a photoabsorbing layer of ternary or quaternary III-V compound semiconductor material, is disclosed. This new photodetector is significant because it exhibits a relatively small dark current and a correspondingly large signal-to-noise ratio. Moreover, the photodetector is readily integrable with electronic integrated circuits and is relatively easy to fabricate.
