Abstract: PROBLEM TO BE SOLVED: To provide an optical modulator having a micromechanical constitution in which operations are conducted by a lower voltage than the optical modulator having a conventional micromechanical constitution. SOLUTION: In a modulator la, a thin film 15 is supported on the upper section of the area of a substrate 10 and at least two electrodes are arranged on the film 5. Each electrode is brought into electrical contact to a controlled voltage source through a shift.register 24 and voltages are successively applied to the electrodes. An optical window 16 is provided between two adjacent electrodes to receive optical signals. If voltage pulses are applied between the substrate 10 and the electrodes during the operations, an electrostatic force is generated, the film 15 is pulled in the direction of the substrate 10 and pulses are generated at the thin film located in the lower section of the electrodes. The mechanical pulses are mutually reinforced and voltage pulses are timely specified so that the pulses having a same value of the total sum of the pulses generated by the electrodes or a displacement are generated in the inner section of the film 15 at the window 16. If the film 15 is displaced from its initial position and moves in the direction of the substrate 10, a change is generated in the optical characteristics of the modulator 1a such as a reflection capability for the optical signals.

Abstract: Carbon particles, such as, carbon fibrils and carbon nanotube molecules, may be assembled into substantially pure aligned fibers by a) dispersing the carbon particles within a curable liquid, b) aligning the carbon particles by flowing the mixture of curable liquid and carbon particles down a tapering tube, and c) curing the flowing mixture of curable liquid and carbon particles in the general vicinity of the end of the tapering tube to form a fiber. The curable liquid may be cured using ultraviolet light. The solidified mixture may be further processed by d) heating the fiber so as to cause the volatile elements of the solidified curable liquid portion to substantially dissipate from the fiber, e) twisting the fiber to increase its density, f) heating the fiber to sinter the carbon particles within the fiber, and g) cladding the fiber. The resulting fiber may then be spooled onto a take-up drum.

Abstract: A passive optical system substantially simultaneously separates light receiv ed at an optical input into three or more output light beams on optical outputs . The output light beams may have intensities that are proportional to intensities of optical projections of the received light onto three or more basis vectors of a tetrahedral basis set of a Stokes space. The system includes either multiple partial polarization splitters or multiple optical interferometers.

Abstract: A micromechanical optical modulator, and methods for operating the modulator are disclosed. The modulator has a membrane supported over a region of a substrate. At least two electrodes, and preferably more, are disposed on the membrane. Each electrode is in electrical contact with a controlled voltage source through a shift register for sequentially applying a voltage to the electrodes. An optical window for receiving an optical signal is defined between two adjacent electrodes. In operation, a voltage pulse is applied to the substrate and each of the electrodes. As the voltage is applied, an electrostatic force is generated, drawing the membrane towards the substrate and thereby generating a mechanical pulse in the membrane beneath each electrode. The pulses are propagated through the membrane to the optical window. The voltage pulses are timed so that the mechanical pulses reinforce one another creating a pulse or displacement in the membrane at the optical window equivalent to the sum of the pulses generated by each electrode. As the membrane is displaced from its initial position and moves toward the substrate, there is a change in an optical property of the modulator, such as its reflectivity to an optical signal. Thus, by changing the position of the optical window, relative to the substrate, an optical signal can be modulated.

Abstract: In one embodiment, an integrated magnetometer has a deformable, electrically conducting beam that is mounted on a substrate and adapted to oscillate with respect to the substrate. When the oscillating beam is exposed to a magnetic field, the magnetic field induces an oscillating electro-motive force that generates an oscillating electrical signal along the beam. The magnetometer has a detection circuit that detects this oscillating electrical signal and, based on the results of this detection, determines the magnetic-field strength and/or the magnetic-field gradient.
