Form birefringence of volume gratings in photopolymers

We investigate experimentally the form birefringence due to photoinduced one- and two-dimensional volume index gratings in DuPont photopolymers. Experimental results on the dispersion of the form birefringence versus the illumination wavelength and the grating period for one-dimensional gratings are...

Description
Summary:We investigate experimentally the form birefringence due to photoinduced one- and two-dimensional volume index gratings in DuPont photopolymers. Experimental results on the dispersion of the form birefringence versus the illumination wavelength and the grating period for one-dimensional gratings are presented. We also investigate the form birefringence due to two-dimensional volume gratings. Positive form birefringence and biaxial form birefringence can be obtained by recording two volume gratings with different grating wave vectors.
