Sm. Silence et al., OPTICAL-PROPERTIES OF POLY(N-VINYLCARBAZOLE)-BASED GUEST-HOST PHOTOREFRACTIVE POLYMER SYSTEMS, Applied optics, 33(11), 1994, pp. 2218-2222
The photorefractive properties of poly(N-vinylcarbazole) doped with a
variety of nonlinear optical chromophores and sensitizing agents are s
urveyed. Steady-state diffraction efficiencies of greater than 10-3 an
d two-beam coupling gain exceeding the absorption loss are found in si
x materials combinations. The effect of the structure of the nonlinear
optical chromophore on the photorefractive properties is discussed.
