All-optical poling kinetics of azophenylcarbazoles influenced by attached anchor
Second order non-linear optical features of anchor attached azophenylcarbazole based derivative 9-(2,3-epoxy)propyl-2-(2,3-epoxy)propoxy-3-(4-nitrophenyl)azo-9H-carbazole dispersed in polycarbonate was investigated. Using all-optical poling technique writing and reading kinetics of second order susceptibility gratings were measured. Theoretical modelling of the experimental results revealed one…
