摘要
An optical communication system that includes a data transmitter which includes: at least one ultraviolet laser source configured to output ultraviolet light energy as an optical beam having an operating bandwidth with at least one communication band; a frequency presence modulation unit including at least one optical component having an ultraviolet coating, the frequency presence modulation unit being configured to: spectrally segregate the bandwidth of the at least one communication band into plural channels, and modulate the bandwidth to selectively produce an ultraviolet optical output signal with wavelengths that correspond to one or more of the channels, wherein a presence and absence of energy within channels of the communication band will constitute an information packet for data communication; and a controller for providing a control signal to the frequency presence modulation unit to spectrally segregate the bandwidth of the at least one communication band into the plural channels.
