    Notes: Abstract The reversible cis-trans photoisomerization of disperse red 1 (DR1) in PMMA thin films has been demonstrated to be strongly polarization sensitive [1]. In this communication two mechanisms are identified: the angular hole burning and the angular redistribution of molecules. It is shown that, in the presence of a DC electric field, the redistribution is not centrosymmetric and produces a poling of the film. The evolution of the second-order nonlinear susceptibility, χ(2), is monitored by measuring the electro-optic effect by attenuated total reflection and by second-harmonic generation.

    Polarization effects in photoisomerization of azo dyes in polymeric films (1991)
    Springer
    Applied physics 53 (1991), S. 121-123

    Notes: Abstract The reversible cis-trans photoisomerization of disperse red 1 (DR1) in PMMA thin films has been demonstrated previously by using the Attenuated Total Reflection (ATR) method. In this communication photoisomerization of DR1 is shown to be strongly polarization sensitive. This new property of dye doped polymeric films could lead to practical applications in integrated optics. A simple molecular interpretation is given. Illumination of a DR1 sample by polarization fringes produces a grating of molecular orientation able to diffract a probe beam.
