摘要： Aspects and embodiments are generally directed to optical systems, receivers, and methods. In one example, an optical receiver includes a plurality of fused fiber optic bundles, at least a first fused fiber optic bundle of the plurality of fused fiber optic bundles positioned to collect optical radiation from a scene, a multi-mode fiber optic cable coupled to each fused fiber optic bundle of the plurality of fused fiber optic bundles, the multi-mode fiber optic cable configured to propagate the collected optical radiation from each of the plurality of fused fiber optic bundles along a length of the multi-mode fiber optic cable, and a photo-detector coupled to the multi-mode fiber optic cable and configured to receive the collected optical radiation. A field of view of each fused fiber optic bundle of the plurality of fused fiber optic bundles may collectively define a substantially omnidirectional field of view of the photo-detector.

摘要： A switch core is set forth that comprises a plurality of duplex switches that are interconnected with a interconnection fabric to implement, for example, strictly non-blocking operation of the switch core for reciprocal traffic. In one embodiment, an N-way reciprocal switch is implemented. The N-way reciprocal switch comprises a plurality of duplex switches numbering N of at least a 1×(N−1) switch type (e.g., the duplex switches have at least N−1 ports available for connection to implement the interconnection fabric). The interconnection fabric interconnects the plurality of duplex switches so that each duplex switch is connected to every other duplex switch used in the interconnection fabric by a single connection. A similar an architecture using switches numbering N of at least a 1×N switch type are also set forth. Still further, a plurality of duplex switches are used to implement an (n,m)-way switch that, in turn, can be used to construct a recursive LM-way switch core and/or recursively expand an existing Clos switch core.

摘要： A reflective optical switch for use in optical systems, such as fiber optic communications networks, is disclosed. The optical switch includes not only signal transmission characteristics, but also signal reflection capability. The optical switch includes a semiconductor substrate having first and second optical signal waveguides disposed thereon. The two waveguides intersect one another at a selected angle to form an intersection region. A thermal element is disposed atop the intersection region and can be activated to alter the index of refraction of a portion of the intersection region. An optical signal passing through the intersection region is diverted from one waveguide to another according to the heating of the intersection region by the thermal element. A reflective component disposed in a terminal end of one of the waveguides reflects selected optical signals back to the source from which they came.

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 the spacing between electrodes is increased without effecting the fill factor of the mirrors by interlacing two sets of tilting platforms, whereby the reflecting portions of both sets of tilting platforms are adjacent one another, while the non-reflecting portions of adjacent platforms are remote from each other.

摘要： An improved waveguide shuttle optical switch design which provides the function of a variable optical attenuator (VOA). A small degree of intentional misalignment of the waveguide will create different levels of optical attenuation. By finely controlling the misalignment of a selected switched position, a single device may be realized that will provide the functions of both switching and attenuating or just attenuation alone. The optical MEMS device utilizes a latching mechanism in association with a thermal drive actuator for aligning a waveguide shuttle platform. The integration of the switching function and the VOA function reduce the optical loss which is otherwise unavoidable when the inevitable alternative of a separate switch and a separate VOA must necessarily be employed. The resultant improved device can also be applied for correcting the difference in optical intensity created by the manufacturing tolerances inherent in the fabrication of array waveguide gratings.

摘要： A buckling actuator has a connecting section of a supporting beam that is provided with a rotatable supporter for allowing a movable member to be stably maintained at one of two switch positions. A substrate, stationary members, rotatable supporters, and supporting beams support a movable member in a shiftable manner in a y-axis direction, such that the movable member can be shifted between first and second switch positions. Moreover, the rotatable supporters are each provided with arm portions which extend in a radial fashion and support the corresponding supporting beam in a rotatable manner. When the movable member is being shifted, each supporting beam scan be rotated without having to bend a corresponding end by a significant amount. Thus, a large barrier ΔE of potential energy of the movable member is set between the first and second switch positions. The movable member can therefore be stably maintained at each of the switch positions even when electric power is not supplied to electrodes. Furthermore, each arm portion prevents the movable member from being displaced in an x-axis direction.

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.
