We present experimental data that show that the greatly improved performance of a new
class of photorefractive polymers [see Donckers et al., Opt. Lett. 18, 1044 (1993)] is too large …

To manifest a photorefractive effect, the polymer must possess a photocharge generator, a
charge transporter, a charge trapping center, and a nonlinear optical (NLO) chromophore …

We investigate in detail the grating properties of a recently discovered organic
photorefractive polymer as a function of electric field by using two-beam coupling. Using an …

We report the first observation of the photorefractive effect in a polymeric material, the electro-
optic polymer bisphenol-A-diglycidylether 4-nitro-1, 2-phenylenediamine made …

The photorefractive (PR) effect is defined as spatial modulation of the index of refraction due
to charge redistribution in an optically nonlinear material. The effect arises when …

Photorefractive (PR) materials are multifunctional materials which combine
photoconductivity and an electro-optic (EO) response to manifest a photorefractive effect. 1 …

Two-beam-coupling gain coefficients exceeding the absorption coefficient are demonstrated
for the first time to our knowledge in an organic photorefractive system. The material is …

It is demonstrated that the microscopic mechanism of the photorefractive (PR) effect in
organic composites with low glass transition temperatures involves the formation of …

A new class of photorefractive polymeric materials is described on the basis of inert polymer
binders doped with a single small molecule species which has the dual function of providing …

▪ Abstract Rapid advances in the field of photorefractive polymers and composites have in
the brief time since their inception in 1991 led to the development of high-performance …
