Paper Abstract

Photorefractive four-wave mixing (FWM) and photoconductivity properties of two new polymers are investigated. One polymer is composed of photoconducting poly(n-vinylcarbazole) (PVK), photosensitizing 2,4,7-trinitro-9-fluorenone (TNF), and optically nonlinear 4-(dicyanovinyl)-N.N-diethylaniline (DCVDEA). Its FWM diffraction efficiency and response time as a function of, respectively, electric field and writing intensity have been determined. With an 80 micrometer thick film, a FWM diffraction efficiency of 7.4 by 10-4 has been obtained. The response time of the polymer is as short as 400 ms at a writing intensity of 0.17 W/cm2. Another polymer is composed of PVK, TNF, and 4-N,N-demethyl- 4'-nitrostilbene (DANS). Its photoconductivity and photocarrier generation efficiency have been determined experimentally at different electric fields and wavelengths.
