Dr. Jer-Shing Huang (Leibniz Institute for Photonic Technology, Jena) delivered a seminar entitled « Hot-spot-assisted coherent nonlinear Raman spectroscopy towards single-molecule resolution and time-resolution » on April 03rd, 2025.

Abstract. This seminar explores advanced Raman spectroscopy techniques that leverage hot spots to achieve single-molecule sensitivity and ultrafast temporal resolution, opening new avenues for molecular-scale investigations.

Bio. Huang is the head of the Research Department of Nanooptics at the Leibniz Institute, where he leads advancements in understanding and engineering nanoscale light-matter interactions using rationally designed nanostructures. Dr. Huang earned his Ph.D. in Chemistry at National Taiwan University in 2004, focusing his dissertation on laser-induced breakdown spectroscopy. He joined Academia Sinica’s Institute of Atomic and Molecular Science, specializing in single-molecule microscopy, before completing postdoctoral work on plasmonic optical nanoantennas and nanocircuits at Julius-Maximilians-Universität Würzburg, Germany. He later served as assistant and tenured associate professor at National Tsing Hua University (NTHU) in Taiwan, earning both outstanding research and teaching awards. In 2016, he moved to IPHT Jena, establishing a thriving research group in nanooptics. Dr. Huang’s research centers on designing nanostructures that control and enhance light-matter interactions, particularly in the UV to near IR spectrum. His expertise encompasses plasmonic nanoantennas, optical nanocircuits, metasurfaces, optical sensors and nanosensors, chiral spectroscopy and imaging, and fluorescent polymer microresonators. His approach combines theoretical modeling, cutting-edge nanofabrication, and advanced spectroscopic methods. Dr. Huang serves on the Editorial Advisory Board of ACS Photonics and is Editor-in-Chief of OPTIK (Elsevier), as well as a SPIE Visiting Lecturer. He maintains adjunct positions at Academia Sinica and National Yang Ming Chiao Tung University in Taiwan, reflecting his international reputation and collaborative outlook.
