POLARIZATION-SENSITIVE HOLOGRAMS FORMED USING DMP-128 PHOTOPOLYMER

The diffraction efficiency of volume holographic gratings can depend s trongly on the state of polarization of the incident light. We have ex perimentally studied the diffraction properties of highly polarization -sensitive, volume holographic gratings in the highly modulated regime formed using DMP-128 photopolymer and have compared data in this regi me to existing theories. We have found that rigorous coupled-wave theo ry accurately predicts experimental measurements of the diffraction ef ficiency in the highly-modulated, polarization-sensitive regime, while a simpler two-wave theory modified to include form birefringence does not.
