Patent ID: 7756424

Claim:
A transmitting system comprising: a processor to process at least one collimated input beam which has been modulated with a data signal to produce multiple time-delayed output taps, the processor being configured to maintain the collimation of the input beam so that the multiple time-delayed output taps maintain the collimation of the input beam, the multiple time-delayed output taps being spatially distributed, spatially distinct and independently phase shifted; an integration lens to receive the time-delayed output taps and to reintegrate the time-delayed output taps into a single integrated encoded beam with a time series chip sequence; an optical fiber to receive the integrated encoded beam from the integration lens and to transmit the integrated encoded beam; and a variable reflectivity surface which decreases in reflectivity along its length and which is configured to impart a desired amplitude profile onto the time-delayed output taps.
