An apparatus is provided that includes a modulator and an optical transmitter coupled to the modulator and configured to emit an optical beam that the modulator is configured to modulate with data. The optical transmitter may thereby be configured to emit the optical beam carrying the data and without artificial confinement for receipt by an optical receiver configured to detect and recover the data from the optical beam. The optical transmitter may be configured to emit the optical beam with a divergence angle greater than 0.1 degrees, and with a photonic efficiency of less than 0.05%. The photonic efficiency may relate a number of photons of the optical beam detectable by the optical receiver, to a number of photons of the optical beam emitted by the optical transmitter.
