Abstract

Nonlinear optical properties of 3, 4, 9, 10-perylenetetracarboxylic dianhydride thin films grown by ultra-high vacuum process of organic molecular beam deposition are characterized by self-diffraction method. We observe a large diffraction efficiency (approximately 10^-4) from a micron thick film and attribute the nonlinearity to a thermal shift in the excitonic absorption feature or free carrier effects.
