Abstract: In one embodiment, a scalable cross-connect switching system and its corresponding method perform a bridging operation by splitting the incoming light signal into at least a first bridged light signal and a second bridged light signal. The first bridged light signal has a power level equal to or substantially greater than a power level of the second bridged light signal. The disproportionate power levels provide low-loss bridging. Light signals based on these bridged light signals are routed through multiple switch fabrics which provide redundancy in case of failure by switching within the switch fabric. To detect failures, a test access port is configured for monitoring multiple optical paths.

Abstract: A monolithically fabricated micromachined structure couples a reference fram e (56) to a dynamic plate (58). Performance of torsional oscillators or scanne rs benefits greatly by coupling the frame (56) to the plate (58) with folded torsional flexure hinges (96) rather than torsion bars. A folded torsion flexure hinge (96) for supporting the plate (58) from the frame (56) is made up of three basic hinge segments (102a, 102b, 102c). Each basic hinge segmen t (102a, 102b, 102c) has a longitudinal axis (98) which is not oriented perpendicular to the rotation axis (62) of the plate (58). An intermediaire region (104) of the folded torsional flexure hinge (96) couples together immediately adjacent ends (106) of the basic hinge segments (102a, 102b, 102c). A basic hinge segment (102b) may include a torsion sensor (108) for measuring angular rotation of the plate (58) about axis (62) with respect to the frame (56).

Abstract: A micro-mirror strip assembly having a plurality of two-dimensional micro-mirror structures with improved deflection and other characteristics is presented. In the micro-mirror structures, electrodes for electrostatic deflection are disposed on conical or quasi-conical entities that are machined, attached or molded into a substrate. The electrodes are quartered approximately parallel to or offset by 45 degrees from rotational axes to form quadrants. Torsion sensors are provided along the axes of rotation to control deflection of the quadrant deflection electrodes.

Abstract: A micromachined, monolithic silicon vane-type flow meter (20) includes a vane (28) from which inwardly projects a hinge. The hinge is provided with torsion bars (24). The hinge supports a vane (28) for rotation about the torsion bars (24). A deflection sensing means, consisting of a torsion sensor (42) incorporated into at least one of the torsion bars (24), senses deflection of the vane (28) responsive to fluid impinging thereupon. The frame (22), the torsion bars (24) and the torsion sensor (42) are all monolithically fabricated in a semiconductor single-crystal silicon layer of a substrate.

Abstract: In general, an optical cross-connect switching system comprising a switch subsystem, an input/output (I/O) subsystem including a plurality of removable, I/O port modules, and a switch control subsystem featuring servo modules. These units collectively operate to provide optical data paths for routing of light signals without conversion from optical to electrical domains and back to optical. Also, the optical cross-connect switching system is scalable because the I/O port modules, servo modules and even features of the switch subsystem may be removed without disruption in system operation.

Abstract: A fiber optic switch (400) includes a fiber optic switching module (100) that receives and fixes ends (104) of optical fibers (106). The module (100) includes numerous reflective light beam deflectors (172) which may be selected as pairs for coupling a beam of light (108) between a pair of optical fibers (106). The module (100) also produces orientation signals from each deflector (172) which indicate its orientation. A portcard (406) included in the switch (400) supplies drive signals to the module (100) for orienting at least one deflector (172). The portcard (406) also receives the orientation signals produced by that deflector (172) together with coordinates that specify an orientation for the deflector (172). The portcard (406) compares the received coordinates with the orientation signals received from the deflector (172) and adjusts the drive signals supplied to the module (100) to reduce any difference between the received coordinates and the orientation signals. The switch (400) also employs optical alignment to precisely orient pairs of deflectors (172) coupling a beam of light (108) between optical fibers (106).
