Abstract: An analog signal processing module includes a processor and a comparator circuit module having a comparator circuit input and a comparator circuit output, the comparator circuit module being configured to receive a first analog signal at the comparator circuit input and generate a digital output, wherein the comparator circuit output is connected to the processor. A digital-to-analog converter (DAC) module is configured to receive a digital output from the processor and convert the digital output to a second analog signal. An operational amplifier (OpAmp) circuit module has an OpAmp circuit input and an OpAmp circuit output, the OpAmp circuit module being configured to receive the second analog signal at the OpAMp circuit input. A feedback loop is formed by the processor, the DAC module, and the OpAMp circuit module, and is configured to implement an amplification function or attenuation function performed by the OpAmp circuit module.

Abstract: An optical communication system having a data transmitter which includes: at least one optical emission device to output light energy as an optical beam having an operating bandwidth; a beam dividing device to receive and divide the operating bandwidth into plural communication bands; a frequency presence modulation unit to: spectrally segregate the bandwidth of at least one communication band into plural channels, and modulate the bandwidth to selectively produce an optical output signal with wavelengths that correspond to one or more of the channels, wherein presence and absence of energy within channels constitute an information packet for data communication; 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; and a telescope to transmit the optical output signal.

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.
