摘要： A holographic optical element (HOE) device is mounted in wireless optical telecommunication system transceiver. The HOE device includes a developed emulsion material having an interference pattern recorded thereon, sandwiched between a pair of elements, such as a pair of clear glass plates. In operation, the HOE device uses the recorded interference pattern to diffract received light rays towards an optical processing unit of the system receiver. A transmitter unit can be positioned at least in part behind the HOE device. An opening in the emulsion material allows a light signal transmitted from the transmitter unit to be substantially unaffected by the recorded interference pattern. The transceiver can also include a spotting scope and an alignment beacon.

摘要： Apparatus and methods for implementing a high-power or high-sensitivity tracking mode of operation in a free-space optical communication system are disclosed. Functions of the high-power or high-sensitivity tracking mode may be implemented in response to one or more engage signals generated and transmitted in response to a sensed inclement weather condition, such as fog or the like, which may interfere with communication of an optical signal between a pair of free-space optical terminals in the free-space optical communication system. Implementation of the high-power or high-sensitivity tracking mode facilitates maintenance of the alignment between the pair of free-space optical terminals throughout the duration of the inclement weather condition to allow data communication to resume fully after the inclement weather condition has diminished.

摘要： An apparatus for transmission of free space optical communication system signals employing a spatially-extended light source and method of using the same. A laser beam source directs an optical signal into a free end of a segment of multimode fiber. As the optical signal passes through the segment of multimode fiber, the optical signal is converted into a mode-scrambled optical signal. This mode-scrambled signal may then be used as a spatially-extended light source that is directed outward as an optical beam through the use of a collimating lens.

摘要： A free space point-to-multipoint optical transceiver has a reflective element and an optical feed mounted on the reflective element. When the optical feed is coupled to a light source, the optical feed is positionable to direct light received from the light source onto a reflective surface of the reflective element. Light directed onto the reflective surface is reflected towards a remote location to be received by a receiver located at the remote location. By adjusting a position of the optical feed, the reflected light is aimed. Therefore, adjusting the position of the optical feed provides a technique to track moving remote locations and/or to target different remote locations.

摘要： A mode scrambler comprises an optical fiber adapter having a diffuser disposed between optical fiber mating ends of the optical fiber adapter. When a single mode optical signal is launched in the mode scrambler, the mode scrambler converts the single mode optical signal to a multimode optical signal that has a substantially even intensity distribution across the modes.

摘要： A method and system for effectuating network routing over primary and backup channels. In one embodiment, a primary link is enabled to transfer customer traffic between network nodes, while a transmission quality of the link is monitored. Upon determining the primary link has entered a marginal state, the primary link is disabled such that the network immediately determines it is unavailable. Test traffic is sent over the primary link while monitoring the transmission quality to determine if the link returns to a non-marginal state, and in response thereto the primary link is re-enabled such that the network immediately determines it is available for routing customer traffic again. In one embodiment, rerouting the customer traffic is effectuated by opening and closing the primary link, such that it appears to the network to be disconnected and reconnected. In one embodiment, the primary link comprises a free space optical (FSO) link.

摘要： A window-mounted positionable collector comprising a base that is secured to a window. An inner rotatable hollow wedge-cut member may be rotated about the base to produce a first degree of freedom, while an outer rotatable hollow wedge-cut member may be rotated about a top end of the inner rotatable hollow wedge-cut member to provide a second degree a freedom. The combination of the first and second degrees of freedom enables the optical axis of an optical collector operatively coupled to the outer rotatable hollow wedge-cut member to be directed along any direction falling within a cone of angulation defined by acute angles corresponding to the angles of the wedge cuts defined in the rotatable hollow wedge cut members. In one embodiment, a cover is connected to a top end of the outer rotatable hollow wedge-cut member to form a sealed volume, whereby the apparatus may be secured to the window by applying a vacuum to the sealed volume.

摘要： Optical transceivers include a diffractive optical element (DOE) attached to a surface of a prism or other optical support. The DOE is configured to direct an input optical signal to a planar or curved reflective surface, or receive an output optical signal from the planar or curved reflective surface at angles greater than a critical angle in the prism. In some examples, the optical support includes one or more curved reflective surfaces and the DOE is a hologram. Such optical transceivers include a reflective surface that is rotatable with respect to the DOE, or with respect to a selected communication direction and the DOE for selection of a transmission or reception direction. The optical supports of such optical transceivers can be mounted to a window, and include a reflective region configured to total internally reflect optical signals. Selection of a communication direction is based on a rotation of the rotatable reflective surface.

摘要： A free space optical tap and multi/demultiplexer unit includes at least one optical unit that can tap off an optical signal from and/or add an input optical signal to a received FSO signal. The optical unit propagates the resulting optical signal, via free space, to a next optical unit of the system. The optical unit can include a holographic grating to diffract a portion of the received FSO signal to an optical detector and/or diffract an input optical signal to form part of a free space optical output signal. In addition, the FSO signal can include component signals of different wavelengths, with each optical unit of the system being wavelength specific to a different one of the wavelengths of the FSO signal.
