    摘要: A mechanical memory transistor includes a substrate having formed thereon a source region and a drain region. An oxide is formed upon a portion of the source region and upon a portion of the drain region. A pull up electrode is positioned above the substrate such that a gap is formed between the pull up electrode and the substrate. A movable gate has a first position and a second position. The movable gate is located in the gap between the pull up electrode and the substrate. The movable gate is in contact with the pull up electrode when the movable gate is in a first position and is in contact with the oxide to form a gate region when the movable gate is in the second position. The movable gate, in conjunction with the source region and the drain region and when the movable gate is in the second position, form a transistor that can be utilized as a non-volatile memory element.

    摘要: A method for fabricating three-dimensional optical waveguides is disclosed. In this method, a single crystal semiconductor layer is grown upon an insulator which has an index of refraction lower than the semiconductor. The semiconductor layer is deposited to a thickness which provides confinement of light propagating in the semiconductor layer in the vertical direction. An effective larger index of refraction over a cross-sectional region of the semiconductor layer is then formed to provide confinement of light in the lateral direction. In the preferred method, the growth of single crystal semiconductor upon the insulator is achieved by a vapor-phase lateral epitaxial overgrowth technique.Devices fabricated according to the method are also disclosed.

    摘要: Liquid crystal photonic devices and microcavities filled with liquid crystal materials are becoming increasingly popular. These devices often present a challenge when it comes to creating a robust alignment layer in pre-assembled cells. Previous research on photo-definable alignment layers has shown that they have limited stability, particularly against subsequent light exposure. A method of infusing a dye into a microcavity to produce an effective photo-definable alignment layer is described, along with a method of utilizing a pre-polymer infused into the microcavity mixed with the liquid crystal to provide photostability. In this method, the polymer layer, formed under optical irradiation of liquid crystal cells, is effectively localized to a thin region near the substrate surface and thus provides a significant improvement in the photostability of the liquid crystal alignment. This versatile alignment layer method, which can be used in microcavities to displays, offers significant promise for new photonics applications.

A moving plate has a plurality of corrugations and a selective finger design. The capacitive switch includes a selective finger that comes into contact with the fixed electrode so as to minimize the stiction between the moving plate and the fixed electrode when the switch is closed. The DC switch comprises a plurality of dimples that are formed on the selective portion of the moving plate and are positioned to come into contact with the fixed electrode when the switch is closed so as to increase the contact force and lower the resistance between the moving plate and fixed electrode.

    摘要: An optical switch device includes a rolling shutter or membrane attached at one of its edges to a substrate near an optical port in the substrate. The rolling shutter can assume one of two states. In a first closed state, the membrane is uncoiled onto the substrate over the port such that light directed at the port impinges on the shutter. In a second open state, the membrane is rolled up away from the port such that light directed at the port impinges on the port. In one embodiment, a mirror is formed on the membrane such that when the membrane is in the closed state over the substrate, light directed at the port is reflected by the mirror. In one configuration, the optical port includes a hole or aperture such light passed through the port without interference. The device can include a latch electrode the far end of the membrane such that when it is rolled out, it can be held in position by a latching voltage applied across the latch electrode and the substrate. Slits can be formed in the membrane to keep the mirror flat by relieving strain in the membrane and to allow gases in proximity to the device to pass through the membrane as it is activated. The shutter can include dimples to minimize the area of contact between the membrane and the substrate to reduce the probability of the two sticking together. The attachment edge of the membrane can be made shorter than its width to reduce distortions in the membrane to keep the mirror flat. A raised annular rim can be provided around the port such that when the shutter is held down over the port it is pulled taut and flat over the rim. This feature is also used to maintain flatness in the mirror. The switch device can be used as part of an array of optical switches.
