Abstract: Millimeter wave radio with phase modulation. In preferred embodiments each of the two radios in a link uses a single aperture to transmit radiation in one of the two bands, and receive radiation in the other of the bands. The counterpart radio used to form a link preferably is almost identical, except for the interchange of the transmit and receive frequencies. Preferred embodiments utilize a modulation scheme in which the radios each receive on-off keyed data and transmit the on-off keyed data encoded in a millimeter wave carrier wave with binary phase shift keying.

Abstract: A method and system for creating and co-aligning a first array of optical beams with a second array of optical beams. In a preferred application the invention is used in a cross connect optical switch. A first set of alignment beams are created and added to and aligned co-axially with each of the first set of parallel collimated cross-connect communication beams. A second set of alignment beams are created and added to and aligned co-axially with each of the second set of parallel collimated cross-connect communication beams. A preferred embodiment includes an injection unit with a “point” infrared light source such as a vertical cavity surface emitting laser (VCSEL) operating in the near infrared at 850 nm and having a divergence of about 30 degrees. The beam from this source is collimated with collimator optics to produce a collimated beam with a cross sectional dimension of about 16 millimeter×16 millimeters. This collimated beam is separated into 128 separate beams with a mask having 128 0.6 mm diameter apertures that are positioned to align the 128 separate parallel beams with the communication beams from a fiber bundle.

Abstract: A system for directing a communication beam from a transmitter at a first location onto an optical target of a receiver at a second location uses a terrestrial free-space optical data link. The system includes an optical fiber which emanates the communication beam at a first wavelength in the intermediate infrared range onto an optical element of the transmitter. The optical element then collimates and directs the communication beam, together with a beacon beam of a second wavelength in the near infrared range, in a common beam along a path toward the receiver. At the second location, the receiver collects the common beam and focuses it to a focal point. A camera in the receiver then receives scattered light of the beacon beam from the focal point to determine a displacement distance between the focal point and the target. The focal point and target are then aligned with each other to reduce the displacement distance to a null and thereby make the focal point of the common beam incident on the target. Accordingly, the communication beam is directed onto the target which may either be an optical detector or another optical fiber.

Abstract: A system and method for establishing a laser link communications system in free space includes first and second terminals which are distanced from each other on an optical path. Each terminal includes a plurality of laser transmitters which together generate a plurality of laser beams, with each of the laser beams carrying a communication signal. Further, each terminal directs its independently generated laser beams along substantially parallel paths. Though their paths are substantially parallel, the transmitted beams generally overlap in the far field, at the other terminal, where they are collected and incoherently summed for reception and analysis of the communication signal.
