摘要： An optical crossbar switch having refractive or reflective components for equalizing beam spreading and diffraction in all the connections. The optical fibers or waveguides coupled to the switch are not staggered, but are parallel as in a conventional fiber array. The refractive component is disposed between the switch and the input optical fibers. Preferably, a similar refractive component is disposed between the output optical fibers and the switch. The refractive component can be a stairstep block made of glass, silicon or silica. Light from each input fiber travels through a well-defined thickness of the stairstep block. Since the block has a refractive index greater than the surrounding atmosphere, the wavelength in reduced within the block, and beam spreading and diffraction are reduced.

摘要： An optical switch module having a movable mirror disposed between two fixed mirrors. All three mirrors are aligned parallel to each other in a linear array to form a crossbar switch. The movable mirror moves between a first position and a second position to selectively couple optical signals between two inputs and two outputs. The basic switch module may be scaled up to form an apparatus that incorporates N movable mirrors and N+1 fixed mirrors, where N is an integer greater than zero. Such an apparatus can accommodate 2N fiber inputs and 2N fiber outputs, e.g., in an optical add/drop multiplexer (OADM). The parallel configuration of the switch module takes advantage of existing lens array and fiber V-groove technology to facilitate integration of the fibers and collimators in the module, thereby reducing the difficulty and cost associated with alignment, assembly, and packaging.

摘要： Methods for directing an optical beam and for making an apparatus for directing an optical beam are described. One such method may include applying a first force to a plate to move the plate from a first angular orientation to a second angular orientation wherein the plate contacts a stop in the second angular orientation. A reflective portion of the plate is stopped from rotating beyond the second angular orientation. A second force can be applied between the plate and the stop to hold the plate against the stop in a plane substantially parallel to a substantially planar surface of the stop. An apparatus for directing an optical beam may be made by coupling an array of plates to a base assembly wherein each plate is movable between a first angular orientation and a second angular orientation.

摘要： Microstructure apparatus and methods are described. An exemplary movable microstructure apparatus includes a base, a plate, and a stop. The plate may be coupled to the base through a flexure, so that the plate is movable between a first angular orientation and a second angular orientation. The stop may be configured to contact the bottom portion of the plate in a contact area when the plate is in the second angular orientation. Alternatively, the stop may be configured to contact the plate in a contact area sized so that upon application of an electrostatic bias between the plate and the stop, a sufficient force holds the plate against the stop. Alternatively, the stop may have a substantially planar surface configured to contact the plate in a contact area sized so that, upon application of a force to the plate substantially normal to the substantially planar surface of the stop, a sufficient force holds the plate against the stop such that the plate lies in a plane substantially parallel to the substantially planar surface of the stop.
