Double-phase-conjugate mirror in CdTe:V with elimination of conical diffraction at 1.54 microm

We have fabricated a double-phase-conjugate mirror (DPCM) in a single crystal of vanadium-doped cadmium telluride. Because of the high gain in the near-infrared region, a DPCM is possible at a telecommunication wavelength of 1.54 microm in this material. Experimental and theoretical thresholds for t...

Description
Summary:We have fabricated a double-phase-conjugate mirror (DPCM) in a single crystal of vanadium-doped cadmium telluride. Because of the high gain in the near-infrared region, a DPCM is possible at a telecommunication wavelength of 1.54 microm in this material. Experimental and theoretical thresholds for the DPCM are compared, and an experimental diffraction efficiency of 7.4% is reported. Conical diffraction has been eliminated by the method of cylindrical lenses. We propose to use this astigmatic configuration to enhance the capacity of interconnections between fibers with a single crystal in a vector-matrix architecture.
