Abstract: A polarization-based generator of duality modulated electromagnetic radiation, and a related method, by which the duality ratio of the energy-based irradiance and wave-based intensity may be selectively altered. A linearly polarized coherent radiation beam is incident on a polarizer configuration. Relative angular alignment of the beam's polarization and the polarizer configuration selectively provides output beams ranging from totally energy-depleted radiation to significantly energy-enriched radiation.

Abstract: A method and apparatus for increasing duality modulation of electromagnetic radiation beyond levels achievable by individual duality modulation generators where duality modulation imparts to radiation a disproportion of irradiance and wave intensity. Various techniques are disclosed for configuring a multiplicity of individual duality modulation generators in a cascade such that initially input radiation acquires cumulative increments of duality modulation upon traversing the cascade of individual generators.

Abstract: A generator of duality modulated radiation and a corresponding method for its use. The generator depletes or enriches the proportion of energy relative to the wave intensity of a beam. Duality modulation is achieved using a single input beam that is incident on a diffractive grating. For a selected grating structure, the angle of incidence, the wavelength of the input beam and the periodicity of the grating are selected to achieve a desired duality modulation in a diffracted output beam.

Abstract: A generator of duality modulated radiation, of which the irradiance, the wave intensity, or both, are varied from ordinarily equivalent levels, either for purposes of providing energy depleted or energy enriched radiation or for purpose of encoding an information signal. Various techniques are disclosed for restoring irradiance levels to “ordinary” levels, or for amplifying irradiance without affecting wave intensity. A communication system employing duality modulated radiation is also disclosed.

Abstract: A generator of energy-depleted radiation and various methods and applications using the energy-depleted radiation. Various embodiments are disclosed of the energy-depleted radiation generator and an energy-restored radiation generator, which permits detection of wave properties of the radiation without regard to the depletion of its energy. The energy-depleted radiation generator functions in one embodiment by selective transmission of destructively interfering radiation. Other embodiments use two-beam coupling or directional coupling to achieve energy depletion. Restoring energy to an energy-depleted radiation beam is accomplished by transferring energy to it from a reference beam, in a beam-to-beam transfer or in an optical amplifier. The invention has important applications in fields such as communications, specimen analysis, photorefractive recording, holography, and other fields in which the reduction of energy content in the associated radiation is advantageous.
