Abstract :
Nanostructured glass is expected to be used for high-function devices. Nanoimprinting is one of the mass fabrication methods of nanostructures; however, it has a disadvantage of a long cycle time. In this paper, we propose and demonstrate a high-throughput method in which only the surfaces of the glass and a mold are heated with a laser. The mold consists of two layers; a layer transparent to light (quartz) and a light-absorption layer (diamond-like carbon). We demonstrated the imprinting of micron- and nanosize patterns on an optical glass and confirmed that the imprinting resolution was approximately 100 nm.
