摘要： A waveguide/MEMS switch adapted to redirect optical signals between output ports based on a phase shift change generated by motion of one or more movable MEMS mirrors incorporated therein. Advantageously, such a switch has a relatively high switching speed and low power consumption. A switch according to one embodiment of the invention includes a planar waveguide device and a planar MEMS device. The MEMS device implements in-plane (i.e., parallel to the plane of that device) translation of the mirrors. As a result, in certain embodiments of the switch, the waveguide and MEMS devices are connected into a compact planar assembly.

摘要： A MEMS device fabricated from a single multi-layered wafer, which alleviates the alignment problem associated with a two-piece prior-art design. In one embodiment, the MEMS device has a stationary part and a movable part rotatably coupled to the stationary part. The stationary part has an electrode and a first conducting structure electrically isolated from the electrode. The movable part has a rotatable plate and a second conducting structure located on the plate and electrically connected to the plate. The mass and location of the second conducting structure are selected such as to compensate for the plate's imbalance with respect to the rotation axis. In addition, at the rest position, the first and second conducting structures form, around the electrode, a substantially continuous barrier adapted to provide electrical shielding for the electrode. The movable part is adapted to rotate with respect to the stationary part in response to a voltage applied between the second conducting structure and the electrode such that the movable part cannot come into physical contact with the electrode during the rotation, which alleviates the snap-down problem inherent to many prior-art devices.

摘要： An integrated device has a spring having at least two split parts that are not in direct electrical contact with each other. The integrated device also has a substrate and a movable part, where both parts of the spring are configured between the substrate and the movable part to support the movable part on the substrate. The two or more split parts of the spring enable two or more independent voltages to be applied to the movable part.

摘要： A representative embodiment of the invention provides a sound-direction detector having a miniature sensor coupled to a signal-processing block. The sensor has (i) a microphone responsive to a sound wave and (ii) a differential pressure sensor (DPS) responsive to a pressure difference induced by the sound wave between two inlet ports located in proximity to the microphone. The signal-processing block applies phase-sensitive detection to the output signal generated by the DPS, while using the output signal generated by the microphone as a reference for the phase-sensitive detection, to measure the pressure difference. The signal-processing block then determines direction to the sound-wave source based on the amplitude of the sound wave at the microphone and the measured pressure difference.

摘要： An optical system having a spatial light modulator (SLM), in which each pixel has an optical cavity and is adapted to: (i) change the intensity of a reflected beam by changing the size of the cavity and (ii) change the phase of the reflected beam by changing the position of the cavity with respect to a reference plane. In one embodiment, the optical system has optics configured to image the apertures of an optical input mask onto the pixels of the SLM and to form an optical spot array by imaging the light reflected by the pixels onto a plane orthogonal to the plane of the mask. Each aperture can be configured to have a transmission pattern to spatially modulate the light imaged onto the corresponding pixel, thereby enabling control of the spatial mode at the corresponding spot in the optical spot array.
