  3. Abstract:
  4. Optical properties of twisted electromagnetic beam propagating in one-dimensional binary dielectric-plasma photonic crystal are investigated. Reflection and transmission spectra by using nonlinear Transfer Matrix Method of Degenerate Four-Wave Mixing are calculated. These characteristics are studied in low intensity, high temperature range of plasma, large Rayleigh range and neglecting the pumps depletion. In our calculation, the standard slowly varying field approximation is employed. The results show that the composite vortex patterns in the left of photonic crystal structure is dependent on the beam vortex charge number, the incident beam frequency and plasma temperature. Also, it is indicated that reflection and transmission may be more than unity for the sake of amplifying through the nonlinear medium. In fact, this structure can be exploited for characterization of phase conjugation in multilayer optical structures and optoelectronic
