ABSTRACT:
A distortion free fiber optic system having a single-mode optical fiber utilized in combination with a semiconductor material mounted in optical alignment therewith. Although it is preferable for the semiconductor material to be adjacent the input end of the fiber, it may, in the alternative, be placed adjacent the output end of the fiber. For appropriate distortion free propagation of a beam of electromagnetic radiation through the optical fiber, the semiconductor material must be receptive to the wavelength of the electromagnetic beam. This can be accomplished by either matching the semiconductor material to the wavelength of the beam or tuning the source of the electromagnetic beam to the excitonic-polariton resonance of the semiconductor crystal.
