Abstract
An example device may include an optical modulator configured to generate an optical beam encoding network data, an optical power amplifier configured to adjust a transmitted power of the optical beam, and a transmit beam angle mechanism configured to adjust a beam direction of the optical beam and to transmit the optical beam to a remote receiver over a free-space optical link. Example devices may include a controller configured to receive backchannel data from the remote receiver and modify a characteristic of the optical beam based on the backchannel data. Various other devices, systems, and methods are also disclosed.
