    摘要: A micro-optical device having an aligned waveguide switch. The device includes a stationary input part, a stationary output part and a movable part. The stationary input part and the stationary output part each have a plurality of input and output waveguides, respectively. The movable part has a plurality of switching waveguides and is movable relative to the stationary input and output parts. A stop block limits movement of the movable part in order to align at least one of the switching waveguides with the applicable input waveguide(s) and output waveguide(s). The movement of the movable part is substantially transverse.

    摘要: A method for forming a gap (16) of a width (d) which meets selected tolerance limits includes forming sidewalls (80, 82) in a microstructure, the sidewalls defining a gap (16) therebetween. The gap has a width defined between the sidewalls. The width of the gap between the sidewalls is determined. Where the determined width of the gap is below the selected tolerance limits for the width of the gap, the sidewalls are consumed to form a gap which meets the selected tolerance limits. The gap may be incorporated in a waveguide device (10) of a microswitch (100) and selectively connect input and output waveguides (130, 132).

    摘要: A device structure is defined in a single-crystal silicon (SCS) layer separated by an insulator layer, such as an oxide layer, from a handle wafer. The SCS can be attached to the insulator by wafer bonding, and is selectively etched, as by photolithographic patterning and dry etching. A sacrificial oxide layer can be deposited on the etched SCS, on which polysilicon can be deposited. A protective oxide layer is deposited, and CMOS circuitry and sensors are integrated. Silicon microstructures with sensors connected to CMOS circuitry are released. In addition, holes can be etched through the sacrificial oxide layer, sacrificial oxide can be deposited on the etched SCS, polysilicon can be deposited on the sacrificial oxide, PSG can be deposited on the polysilicon layer, which both can then be patterned.

    摘要: A micro spectrophotometer is monolithically constructed on a silicon substrate. The spectrophotometer includes a concave grating, which is used for dispersing optical waves as well as focusing reflected light onto a photodiode array sited on a silicon bridge. The silicon bridge is bent 90° from the surface of the silicon substrate in order to orthogonally intersect the output light from the grating. A precision notch is defined in the silicon substrate for coupling to an optical input fiber. Signal processing circuitry is etched on the substrate using conventional CMOS processes for initial processing of information received from the photodiode array.
