  • An ultrafast terahertz (THz) scanning tunnelling microscope (STM) with subpicosecond time resolution and nanometre spatial resolution has been developed. THz pulses are coupled to the metal tip of a commercial STM and THz-pulse-induced tunnelling is observed in the STM. The THz-STM can directly image ultrafast carrier capture by a single InAs nanodot.

  • Understanding the fundamental limits to photonic design is both theoretically important and critical to the development of future high-performance photonic devices. This Review surveys progress made in this area and discusses an emerging general framework for evaluating photonic design limits based on conservation principles and optimization theory.
