    摘要： In an optical LAN system, an optical connector is provided between the input and output optical fiber cables and each of the node devices. The optical connector includes a movable body (a switch body) having a prism. The movable body is switched selectively between a first position (a first state) at which the input and output optical fiber cables are optically connected to the node device and a second position (a second state) in which the input optical fiber cable and the output optical fiber cable are optically connected to each other in such a manner as to bypass the node device. This arrangement suppresses a network crash by means of a relatively simple configuration.

    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 thermal optical switching cell for controlling the transmission of light through optical channels (21, 22, 23, 24) that includes a switching conduit (60) containing a working fluid (41) that is index of refraction matched to the optical channels and an amount of light diverting material (42) that is substantially immiscible in the working fluid and is not index of refraction matched to the optical channels. Micro heaters (31, 32) generate pressure pulses in the working fluid for moving the light diverting material between switch states.

    摘要： An optical multilayer structure (1) has a transparent substrate, a transparent first layer (11) in contact with the substrate (10), a gap portion (12) having a changeable size capable of causing an optical interference phenomenon, and a transparent second layer (13). By changing the size of the gap portion (12), an amount of reflection, transmission, or absorption of incident light can be changed. Also in a visible light area, high response is realized. Consequently, the optical multilayer structure can be suitably used for an image display.
    In one alternative the optical multilayer structure may be obtained by stacking, on a substrate, a first transparent layer made of a material having a high refractive index such as TiO 2 (n = 2.40), a second transparent layer made of a material having a low refractive index such as MgF 2 (n = 1.38), a gap portion having a changeable size capable of causing an optical interference phenomenon, and a third transparent layer made of a material having a high refractive index such as TiO 2 .
    The structure may be used in an optical switching device and in an image display.

    摘要： An optical multilayer structure (1) has a substrate, a light-absorbing first layer (11) in contact with the substrate (10), a gap portion (12) having a changeable size capable of causing an optical interference phenomenon, and a second layer (13). By changing the size of the gap portion (12), an amount of reflection, transmission, or absorption of incident light can be changed. For example, the substrate (10) is made of carbon (C), the first layer (11) is made of tantalum (Ta), and the second layer (13) is made of silicon nitride (Si 3 N 4 ). Also in a visible light area, high response is realized. Consequently, the optical multilayer structure can be suitably used for an image display.
    In one alternative the optical multilayer structure may be obtained by stacking, on a substrate made of a metal such as chromium (Cr), a first transparent layer made of a material having a high refractive index such as TiO 2 (n = 2.40), a second transparent layer made of a material having a low refractive index such as MgF 2 (n = 1.38), a gap portion having a changeable size capable of causing an optical interference phenomenon, and a third transparent layer made of a material having a high refractive index such as TiO 2 .
