Abstract

In this work, we explore the potential of CdSe based quantum dots (QDs) as materials for nonlinear optical applications. The characterization of core and coreshell type QDs in the nonlinear optical regime is conducted both in solution and within hybrid solgel matrices. Such hybrid QD/solgel matrices are found to retain the optical properties of the QDs while allowing for improved QD processability and stability. The exploitation of these properties is demonstrated in two QD/solgel based optical device prototypes: (i) the optical limiter and (ii) the upconverted laser.
