摘要： A communication system includes a plurality of nodes and a plurality of point-to-point links that interconnect the plurality of nodes into a network. Each node includes an optical switch to controllably route a plurality of in-ports of the optical switch into a plurality of out-ports of the optical switch. Each point-to-point link includes a free space optical channel. A first free space optical channel couples to a first node through a receive path and through a transmit path. The receive path couples to a respective in-port of the optical switch of the first node, and the transmit path couples to a respective out-port of the optical switch of the first node. In an alternative embodiment, a communication hub includes a plurality of neighborhood links to corresponding users, an optical switch coupled to the plurality of neighborhood links, and a trunk coupled between the optical switch and a free space optical channel link to the network. A method of communicating in a network having plural links includes sensing the presence of a received signal failure by monitoring channel losses in a first link the received signal failure resulting from at least one of rain and fog. The method further includes sending data in a free space optical channel of the first link when the received signal failure sensed is due to rain and sending the data in an RF channel of the first link when the received signal failure sensed is due to fog.

摘要： A free space communication system includes first and second terminals, and the first terminal includes a transmitter to transmit an input signal. The transmitter has plural laser sources, at least one optical delay line and a telescope. Each laser source modulates the input signal onto a wavelength that is distinct from a wavelength of each other laser source. The plural laser sources include a first laser source and at least one other laser source, and the at least one optical delay line is coupled to a respective output of the at least one other laser source. The telescope projects an output of the first laser source and an output of each of the at least one optical delay line toward the second terminal. Alternatively, a free space communication system includes first and second terminals, and the first terminal includes a transmitter to transmit an input signal. The transmitter has at least one electrical delay line, plural laser sources and a telescope. The at least one electrical delay line delays the input signal. The plural laser sources include a first laser source and at least one other laser source, the first laser source modulates the input signal onto a first wavelength, and each of the at least one other laser source modulates an output of a corresponding electrical delay line onto a wavelength that is distinct from the first wavelength. The telescope projects an output of each of the plural laser sources toward the second terminal.

摘要： A method and apparatus for providing eye-scan authentication using an adaptive liquid lens are disclosed. For example, in one embodiment, the method receives a request for eye-scan authentication from a mobile endpoint device of a user, wherein the request comprises a first retinal image of the user captured using an adaptive liquid lens of the mobile endpoint device. The method obtains a second retinal image of the user, wherein the second retinal image is a stored retinal image of the user. The method authenticates the first retinal image against the second retinal image. In another embodiment, the method captures a first retinal image of a user via a mobile endpoint device of the user, wherein the mobile endpoint device comprises an adaptive liquid lens. The method then sends a request for eye-scan authentication from the mobile endpoint device over a network, wherein the request comprises the first retinal image.
