Summary:In this work, we are demonstrating optical functionalities obtained with colloidal CdTe nanocrystals. These functionalities are based on our experimentally observed huge, saturable, and controlled nonlinear optical properties of CdTe nanocrystals, in the case of strong quantum confinement and near resonant interaction with the excitation light. Our investigation considered two basic types of functionalities, optical limiting and phase modulation, presenting experimental proof of concepts. These types of functionalities are of special interest for integrated optical devices with applications in imaging and telecom.
