An efficient and precise tool for steering on‐demand the periodicity and amplitude of electro‐modulations based on solid‐state is of great importance for quantum engineering. In Cu 2 O crystal, the excitons created by electromagnetic waves can be used to design a flexible device which enables the control of absorption oscillations above the gap. The influence of exterior parameters such as temperature and electric field, which influence the dynamic of these oscillations, is discussed.
