Claim:
1. A communications system, comprising: 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, the POLG comprising: a light source configured to emit light having a predetermined wavelength; a polarization apparatus configured to prepare light from the light source into particular states of polarization; 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; and an electrical oscillator configured to periodically apply an electric field to the phase modulator.
