Paper Abstract

Nonlinear optical (NLO) polymeric films are targeted for photonics applications including optical switches and frequency doubling devices. This work focused on improving upon the NLO activity of these materials by using a composite prepared from a χ 2 active aligned biopolymer and a χ3 active mixture of a donor/acceptor tricyanovinylaniline dye (TCVA) chromophore and a silver metal colloid (Ag). Second harmonic generation was obtained by poling the biopolymer poly-L-benzyl- glutamate. The χ2 values ranged from 5.4x10-11 esu to 2.4x10-10 esu given varying poling voltages of 1 to 3 kv/cm. The p- tricyanovinylaniline dye exhibited large third-order NLO responses when incorporated into polycarbonate films. The χ3 values varied by orders of magnitude ranging from 6x10-12 to 2x10-10 esu depending on the amount of TCVA and silver concentrations in the polycarbonate films.
