In this paper we fabricate nonlinear optical nanocomposite based on CdSe quantum dots mixed with commercial photoresist SU-8, which can be structured by two-photon polymerization lithography. The distribution of quantum dots in the polymer was measured by transmission electron microscopy. Nonlinear optical properties of nanocomposite films were studied by third harmonic generation technique. We estimated the nonlinear cubic susceptibility of our nanocomposite.
