摘要： A free-space wireless optical communication system is disclosed that utilizes a telescope design having aspherical mirrors, such as a Ritchey-Chretien (RC) telescope. RC telescopes are characterized by a concave primary mirror and a convex secondary mirror each having a hyperbolic shape. The disclosed mirror configuration provides a larger focal plane that allows for automatic alignment between a transmitter and receiver with a stationary or fixed mirror design, further contributing to a lower fabrication cost. Among other benefits, the larger focal plane permits an n×n fiber array to be positioned in the focal plane of the RC optical telescope, thereby enabling point-to-multipoint communications with a single optical telescope. Each fiber in the n×n fiber array of a transmitting telescope can be focused on a different receiving telescope in a wireless optical communication system. In this manner, each fiber in the n×n fiber array sends optical energy over a distinct path to address a given receiving telescope. Likewise, for a multipoint-to-point communication system, an n×n fiber array can be positioned in the focl plane 330 of the RC optical receiving telescope, with each fiber in the n×n fiber array receiving optical energy over a distinct path from a given transmitting telescope. A number of fabrication techniques are also disclosed that permit the optical telescopes of the present invention to be fabricated at a reasonable cost that permits such optical telescopes to be deployed in wireless optical communication systems.

摘要： Enhanced alignment of a mechanical optical switch is achievable using two optical fiber structures containing corresponding arrays of optical fibers fixed to first and second substrates cleaved from a common substrate. In an exemplary embodiment, an array of optical fibers is fixed to a common substrate substantially parallel to one another. The resulting structure is cleaved across the optical fiber array to produce cleaved structures. The enhanced optical fiber alignment at the cleaved edges is provided by securing particular respective surfaces of the cleaved substrates to surfaces of two bases aligned in a common plane. Such enhanced alignment occurs in a direction normal to the plane of the surfaces of the bases. Alignment of the optical fibers in a direction parallel to this plane and optical connections between optical fibers of the respective structures occurs by moving the second cleaved structure relative to the first cleaved structure in a direction along the cleaved edges.

摘要： An optical planar waveguide notch filter employs a waveguide with first, second and third regions. The first and third regions have structures for propagating an optical signal in a first transmission mode. The second region is located between the first and third regions and has a structure in which an optical signal propagates in the first transmission mode as well as at least one other higher order transmission mode. The structure of the second region further couples a particular wavelength band of the signal propagating in the first transmission mode to at least one of the other transmission modes. This coupling causes an attenuation of energy of such bandwidth in the signal propagating in the first transmission mode. As a result, the signal propagating from the second region to the third region in the first transmission mode is a notch filtered signal possessing an attenuation at the particular wavelength band.

摘要： A method of connecting arrays of optical wavepaths is described employing externally located connector pads. After optically aligning the arrays to be connected, the connector pads are bonded to the arrays and then to each other. In the preferred embodiments, the pads, which typically are thin silicon wafers, and the arrays are metalized and then soldered together. The use of connector pads to connect arrays of optical transmission paths results in sturdy, stable connections. The technique is fast, simple and inexpensive, and is consistent with current alignment procedures. By using solder to secure the pads to the arrays and to each other, connections can be undone and then redone. Inasmuch as all connections are external to the optical paths, there is no deterioration of the optical connections with time.

摘要： An acousto-optic silica optical circuit switch that selectively routes signals to one of two outputs includes a surface-acoustic-wave source and a coupler waveguide structure formed within silica glass. The waveguide structure includes a single mode input section connected to a multimode section connected to first and second single mode output sections. The first output section has a structure capable of accepting power from an optical signal propagating in a first transmission mode of the multimode section, and the second output section has a structure capable of accepting power from an optical signal propagating in a second transmission mode in said multimode section. In operation, RF excitation is selectively provided to the SAW source to selectively cause coupling of the first and second transmission modes in the multimode section. As a consequence, an optical signal launched in the input section propagates through the multimode section to the first output section in the first transmission mode of the waveguide structure, or alternatively, such launched optical signal is coupled to the second transmission mode in the multimode section such that its power is transferred to the second transmission mode to propagate into the second output section.

摘要： In many assembly applications of optical arrays, a bridging member is bonded to the arrays to hold them securely. It has been found that a pad made of layers of glass and silicon provides an efficient heat transmitting structure for this purpose. Because glass is absorbent to laser radiation at 10.6 .mu.m, it absorbs all the incident laser radiation, and imparts the heat generated to the silicon, which transmits it uniformly over its entire surface. The heat can then be used to melt solder or to heat-cure an adhesive, thereby affecting a robust mechanical bond in an efficient and rapid manner.

摘要： A method and apparatus are disclosed for aligning and maintaining the alignment of the transmitting unit and the receiving unit in an optical wireless communication system. The receiving unit includes an optical bundle positioned at the focal point of an objective optic element. The optical bundle is comprised of an array of optical fibers, arranged surrounding the receiving fiber. The receiving unit also includes a number of detectors that measure the optical signal strength on a corresponding fiber in the optical bundle. The array of fibers is used to detect the location of the received signal relative to the receiving optical fiber and to provide feedback to adjust the orientation of the optical bundle to optimize the received signal strength. When misalignment occurs between the received signal and the receiving fiber, some of the incident received signal will be captured by one or more of the outer optical fibers. The amplitude of each of the generated signals are then compared to each other, thereby giving a direction in which to drive the optical bundle back into alignment with the received signal. The present invention provides automatic tracking using the information-carrying optical signal, without the need for a separate laser.

摘要： A free space optical communication system is disclosed whereby a transmit telescope and a receive telescope are aligned such that the point of maximum power of the received light beam is incident upon the optical fiber located at a specific point on the focal plane of the receive telescope. Such incidence is achieved by causing the transmitted beam to diverge by moving the transmit optical fiber to a point in front of the focal plane of the transmit telescope until at least a portion of the beam is incident upon the receive optical fiber. The transmit telescope and/or the receive telescope (or, alternatively, only the respective optical fibers of those telescopes) are then moved such that the point of maximum received power for that degree of divergence is incident upon the receive optical fiber. The transmit optical fiber, in response to received power measurements at the receive telescope, then incrementally moves back toward the focal plane of the transmit telescope thereby reducing the degree of divergence and achieving a greater signal per unit area at the receive telescope. As the divergence is reduced, the position of the either the transmit telescope and/or the receive telescope (or, respectively, the optical fibers) is incrementally adjusted to maximize the received power of the received signal which is incident upon the receive optical fiber for each degree of divergence. By monitoring received signal power this iterative process continues until the transmit and receive telescopes are aligned such that the transmitted beam is focused so as to maximize the received power that is incident upon the receive optical fiber.
