    摘要： A micro-electro-mechanical (MEMs) mirror device for use in an optical switch is disclosed. A "piano"-style MEMs device includes an elongated platform pivotally mounted proximate the middle thereof by a torsional hinge. The middle portion of the platform and the torsional hinge have a combined width less than the width of the rest of the platform, whereby several of these "piano" MEMs devices can be positioned adjacent each other pivotally mounted about the same axis with only a relatively small air gap therebetween. In a preferred embodiment of the present invention specially designed for wavelength switching applications, a greater range of arcuate motion for a mirror mounted thereon is provided by enabling the platform to rotate about two perpendicular axes. The MEMs mirror device according to the preferred embodiment of the present invention enables the mirror to tilt about two perpendicular axes, by the use of an "internal" gimbal ring construction, which ensures that a plurality of adjacent mirror devices have a high fill factor, without having to rely on complicated and costly manufacturing processes. To limit the amount of electrical crosstalk between adjacent mirrors, shielding (41,42) can be positioned between the electrodes. The shielding can extend upwardly from the substrate and/or downwardly from the undersurface of the mirrors. When both types of shielding are provided, one set is offset from the other to prevent abutment thereof, and to enable an overlapping effect, which enhances the protection.

    摘要： A configurable add/drop optical system is disclosed for demulitplexing, adding and/or dropping closely spaced channels carrying optically encoded data. A composite optical signal having data channels corresponding to centre wavelengths λ1, λ2, λ3, λ4, ... λn are separated into two composite optical signals of first of which comprises data channels corresponding to centre wavelengths λ1, λ3, ... λn and a second which comprises data channels corresponding to centre wavelengths λ2, λ4, ... λn-1, by passing the composite signal through an interleaver circuit in a demultiplexing mode of operation. Two such interleaver circuits are optically coupled to one another and controllable, tunable Bragg gratings disposed therebetween are used to route demultiplexed signals along preferred signal paths.

    摘要： A method and circuit is disclosed wherein two waveguides coupled to an optical resonant ring resonator are further coupled such that beams propagating therein interfere with one another to provide a desired output response. In one embodiment, multiplexed channels of light can be demultiplexed by the device described heretofore, or alternatively, the phase relationship between these two beams can be altered prior to their being combined to provide, for example, a linearised output response useful in applications such as wavelength locking. By varying the reflectivity of the FSR and the coupling ratios and/or by varying the phase relationship between the two beams, a variety of desired output responses can be realised. By providing suitable coupling ratios and providing optical path lengths of the two waveguides which are identical between the ring resonator and the couplers coupling the two waveguides as well as having the couplers placed 180 degrees opposite to each other, an interleaver/de-interleaver function is realised. In other embodiments, different forms of optical cavity resonators (etalons) are used instead of the ring resonator.
