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.

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

There is described a cMUT array with transducer elements which include a plurality of cells with membranes formed on one surface of a wafer. Voltages applied between said spaced electrodes drive said membranes. The voltages applied to said electrodes are applied from the opposite surface of the wafer through the wafer and through vias formed in the wafer.
