Dispersion of the third order optical nonlinearity & all-optical switching figures of merit in molecularly engineered polymers

Abstract

Solid state and solution measurements of the effective third order nonlinear absorption and refraction, have been earned out on poly (2,5-dioctyloxy-paraphenylene-vinylene-co-2,5- pyridinyl) (Pyridinyl PAV), poly (2,5-dioctyloxy-paraphenylene-vinylene-co-2,5-thienyl) (Thienyl-PAV), poly (2,5-dioctyloxy-paraphenylene-ethynylene-co-2,5-pyridinyl) (Pyridinyl-PAE) and poly (2,5-dioctyloxy-paraphenylene-ethynylene-co-2,5-thienyl) (Thienyl-PAE) using the Z-Scan experimental technique.
