Abstract
The photorefractive properties of polymer composites based on aromatic polyimide and single-wall carbon nanotubes are studied using radiation at a wavelength of 1064 nm. It is found that the nanotubes possess photoelectric sensitivity in this spectral region and that the kinetic photorefractive characteristics of the polymer composites are entirely determined by the photogeneration and charge transport characteristics of the layers. The two-beam gain coefficient of the signal beam measured for a composite consisting of aromatic polyimide and 0.25 wt % of single-wall carbon nanotubes in a constant electric field E 0 = 79 V/μm is equal to 84 cm−1 and exceeds the optical absorption coefficient by 59 cm−1. The refractive index modulation is equal to Δn = 0.004 at E 0 = 54 V/μm.
