Abstract: An optical communication system includes a data transmitter. The data transmitter includes at least one optical emission device to output light energy as an optical beam having an operating bandwidth; a beam dividing device arranged to divide the operating bandwidth of the optical beam into bandwidth portions of plural communication bands; an array of graphene switches to: spectrally segregate a bandwidth portion of at least one communication band into plural channels by adjusting at least one graphene switch, and modulate the bandwidth portion to selectively produce an 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. The system includes a focusing grating to receive and focus a first set of wavelengths of the optical output signal reflected by the array of graphene switches.

Abstract: An optical communication system that includes a data transmitter. The data transmitter includes at least one optical emission device configured to output light energy as an optical beam having an operating bandwidth; a beam dividing device arranged to receive and divide the operating bandwidth of the optical beam into bandwidth portions of plural communication bands; a focusing grating; and a digital mirror array having a plurality of digital mirrors. In an imaging mode, the optical communication system is configured to perform hyperspectral imaging by setting all of the plurality of digital mirrors to positions that transmit all wavelengths of a communication band among the plural communication bands to the focusing grating.
