Paper Abstract

Phase change material Sb2Te3 has been proved to possess a strong nonlinear saturation absorption effect, which could produce a dynamic and reversible optical pinhole channel as the origin of breaking through the diffraction limit. In this work, a pump–probe experimental setup is constructed to explore the transient formation process of the dynamic and reversible optical pinhole channel, and the transient transmission and reflection light intensities of the Sb2Te3 are measured directly. The results show that Sb2Te3 is an appropriate material for the mask layer of super resolution nano-optical fabrication.
