Terahertz  Optics  Lab

We have been conducting research on optical and terahertz spectroscopy using ultrafast lasers at the Sensor System Research Center, KIST and KU-KIST graduate school of converging science and technology, Korea University. The research topic covers various spectroscopy techniques in ultrabroadband wavelength regimes including visible, infrared, and terahertz, to investigate optical characteristics of various semiconductors, metals, and bio/chemical materials. Especially, a novel concept of hybrid optical spectroscopy system with nanoscale metamaterials can show highly sensitive and selective detection performance, applicable for non-contact and label-free molecule sensing and imaging. We are also studying the electro-optical properties occurring in ultrashort time in various semiconductor thin films and 2D materials, and applying them to fabricate various devices.
