In this paper we report on fabrication of a nanocomposite based on CdSe quantum dots mixed with commercial photoresist ORMOCOMP and proved its high structurability by direct laser writing. The distribution of quantum dots was visualised by transmission electron microscopy and the quality and geometrical parameters of the structures were studied by optical and atomic force microscopy. We manufactured a novel photonic device for Bloch surface electromagnetic waves in photonic crystals and thoroughly studied their propagation by both leakage microscopy and back focal plane imaging methods. By z-scan method we measured the nonlinear Kerr coefficient of quantum dots. Its high value makes the manufactured photonic device promising for all-optical switching applications.
