This invention provides optical devices with an organic nonlinear optical component which is a transparent medium of a wholly aromatic polymer which exhibits a third order nonlinear optical susceptibility χ (3) of at least about 1 x 10-12esu. n Illustrative of an invention embodiment is an ultrafast all-optical gate device with a transparent poly([benzo-(1,2-d:4,5-d')bisthiazole-2,6-diyl]-1,4-phenylene) optical component which exhibits a third order nonlinear optical susceptibility χ (3) of 10 x 10 -12 esu. |
