Prof. Martin Wegener Karlsruhe Institute of Technology Two-photon based 3D laser printing routinely allows for the making of complex three-dimensional sub-micrometer and nanometer structures and has become a mature, widespread, and commercially available technology. After briefly reviewing the basic principle and the state-of-the-art, I focus on recent progress in my group. This includes replacing two-photon […]

Q-Han Park Korea University Waves, both classical and quantum, are reflected when they encounter different media or potential regions. Reflection is a fundamental property of waves underlying numerous scientific applications. Nevertheless, in many cases removing reflection is a key issue to secure transmission and increase device efficiencies. Since the early works of Brewster and Rayleigh, […]
