    摘要： An optical attenuator for use in optical power regulation uses a shutter to control the insertion loss of a gap in a pair of substantially coaxially aligned waveguides, for example a pair of optical fibers. The shutter is part of a MEMS accuator device and is coupled to the movable one of a pair of spaced plates, the movable plate being movable by a voltage applied between the pair of plates. To regulate the power, a small portion of the optical power is abstracted and used to derive a control voltage that is applied to the optical attenuator for varying the attenuation inserted in the optical wave path.

    摘要： A WDM add/drop device for use in an optic communications system for adding and dropping optical wavelengths from a multiple-wavelength optical system. The device includes a set of lenses, a planar grating wavelength multiplexer and a micromirror array switchable for individual wavelengths of the multiple-wavelength signal between a transmit mode and a reflect mode. The grating angularly demultiplexes a multiple-wavelength optical signal in a first direction and the individual wavelengths are processed by the micromirror array and directed to the grating in a second direction. The micromirror array will either reflect select wavelengths to a first port or transmit select wavelengths to a second port. In a preferred embodiment, ports on a first multiport circulator input the multiple-wavelength optical signal to the WDM add/drop device and output the multiple-wavelength optical signal from the WDM add/drop device. A second multiport circulator provides to-be-added wavelengths to the WDM add/drop device and removes to-be-dropped wavelengths from the WDM add/drop device.

Tapering of the fiber ends allow the ends to be positioned in close proximity to one another to yield an optical switch with low insertion loss. In one embodiment the optical switch comprises: (1) four optical waveguides each having a tapered end comprising two tapered edges and disposed on a support such that each tapered edge of each waveguide is in opposed and near-abutting relation with a tapered edge of another optical waveguide, said near abutment defining a space between each pair of opposes tapered edges; (2) a first electromechanical actuator operable to move at least a first optical device into and out of a path of an optical signal travelling between two of the waveguides, wherein the first optical device moves in the space between a first pair of opposed tapered edges; and (3) a second electromechanical actuator operable to move at least a second optical device into and out of the path of the optical signal, wherein the second optical device moves in the space between a second pair of opposed tapered edges, wherein one tapered edge of the first pair and one tapered edge of the second pair are common to one of the optical waveguides.

    摘要： An article comprising a multi-port variable capacitor is disclosed. In one embodiment, a movable plate is suspended above at least a first and a second, fixed, electrically-isolated electrode. The first electrode is electrically connected to a bias supply, and the second electrode is electrically connected to an AC signal-carrying line. As bias is applied across the first electrode and the movable plate, an electrostatic attraction is developed therebetween that causes the movable plate to move downwardly towards the first electrode. The capacitance of the variable capacitor increases as the separation distance between the movable plate and the fixed electrodes decreases. Unlike conventional variable capacitors, in the present multi-port variable capacitors, the bias (delivered via the first electrode) and the signal (delivered via the second electrode) are electrically isolated from one another. As such, the bias (DC) and signal (AC) paths are advantageously electrically isolated. In an additional embodiment, the movable plate of the present variable capacitor is operable to tilt. The ability to tilt provides additional “signal processing” (i.e., logic) capabilities to the present multi-port variable capacitors. In additional embodiments, an article in accordance with the present teachings comprises a monolithically-integrable, tunable LC circuit, and a variable-frequency oscillator. In such LC circuits and oscillators, the multi-port variable capacitor described herein is used to tune the resonant frequency of the circuit.
