摘要： A 1.times.n optical deflection switch has an array of k transmissive light deflectors to switch an incident light beam into one of n=2.sup.k directions. The switch can steer the light through the deflectors into one of a plurality of beam directions, by selectively individually inserting them into the light path. One embodiment uses four glass rectangular blocks as light deflectors having parallel upper and lower surfaces oriented at a predetermined oblique angle to the incident light beam. The thicknesses of the blocks follow an increasing order in proportion to successive powers of 2, i.e. t, 2t, 4t and 8t, giving a total of 16 switching positions. Another embodiment uses two arrays of 4-block switches, and selectively activates blocks from either array to provide a 1.times.32 switch. Yet, another embodiment uses four stepped deflectors each having two selectable sections of dissimilar thicknesses to give a total of 15 switching positions.

摘要： An optical beam path directing system has a field-flattening optically transmissive wedge installed in spatially dispersed beam paths upstream of the planar surface of a micro electro-mechanical switch (MEMS) or liquid crystal array. The parameters of the field-flattening wedge and its location in the diffracted beam paths are defined such that the wedge effectively rotates a ‘best fit’ planar surface approximation of the curvilinear focal plane of a concave reflector into coplanar coincidence with the optical signal-receiving surface of the MEMS. As a result, loss variation is essentially flat and minimized across the optical signal transmission band.

The switch has a transmissive wedge-shaped switching element disposed between the GRIN lenses. When the switching element is disposed in the path between the GRIN lenses, a single connection is established between a port of the first GRIN lens and a port of the second GRIN lens, while light is prevented from coupling between the remaining ports.

摘要： A control system is designed to control an optical cross-connect having a switch core defined by first and second independently movable beam deflectors capable of selectively defining an optical path between a pair of ports of the optical cross-connect. An optical element having optical power is arranged in a propagation path of light beams between the first and second beam deflectors. The control system includes a pilot light source, an optical sensor associated with each beam deflector, and a feedback path. The a pilot light source inserts a pilot light into the switch core colinearly with live traffic. The optical sensor detects a predetermined geometric property of the pilot light emerging from the switch core. This predetermined geometric property is unambiguously associated with an angular position of the associated beam deflector. The feedback path actively controls a position of the associated beam deflector based on the detected geometric property.

摘要： A clutch hydraulic actuator system having a vibration damper provided in the system between a master cylinder and a slave cylinder of the system. The damper includes an elastomeric diaphragm and a spring steel diaphragm. One face of the elastomeric diaphragm is in fluid communication with hydraulic fluid in the system so that the elastomeric diaphragm may deflect in response to low frequency vibrations transmitted through hydraulic fluid in the system to effect damping of the low frequency vibrations. The spring steel diaphragm is positioned in the system generally parallel to and proximate the other face of the elastomeric diaphragm so as to form a backup for the elastomeric diaphragm so that the elastomeric diaphragm may deform against the spring steel diaphragm in response to high frequency vibrations transmitted through the hydraulic fluid to cause deflection of the spring steel diaphragm to effect damping of the high frequency vibrations.

摘要： Broad wavelength tuning range are achieved in an effectively reset-free, optical, automatic polarization controller by providing a device and method for varying the polarization of an input beam of light. A block of electro-optic material has two pairs of electrodes for applying a voltage across the block. Light is launched into an input end of the block for receiving the input beam of light. A controller controls a quadrature voltage applied to the first and a second pair of electrodes; the quadrature voltage has the form of a magnitude and an angle. The quadrature voltage can be varied in such a manner as to orient a given electric field within the electro-optic material through a plurality of angles, for example between 0 and 2&pgr; radians; the magnitude of the quadrature voltage can be set to create an arbitrary retardance from 0 to 2&pgr;. Any output polarization state can be realized by appropriately varying the magnitude and angle of the voltage applied to the Vx and Vy electrodes.
