Abstract
In one aspect, the present disclosure relates to a communications system which, in one embodiment, includes a phase-correlated, orthogonally-polarized, light-stream generator (POLG) for preparing light into phase coherent light streams having defined states of polarization and spectral composition. In one embodiment, the POLG includes a light source configured to emit light having a predetermined wavelength and a polarization apparatus configured to prepare light from the light source into particular states of polarization. The POLG also includes a phase modulator configured to produce light having a plurality of wavelengths and configured to retard the phase of propagation of light with a first state of linear polarization while not retarding the phase of light with a state of linear polarization orthogonal to the first state of linear polarization when an external electric field is applied. The POLG also includes an electrical oscillator configured to periodically apply an electric field to the phase modulator.
