Optical manipulation on the nano-scale, or nanophotonics, has become a critical research area, as researchers seek ways to meet the ever-increasing demand for information processing and communications. The ability to control and manipulate light on the nanometer scale will lead to numerous applications including data communication, imaging, ranging, sensing, spectroscopy, and quantum and neural circuits (think LIDAR—light detection and ranging—for self-driving cars and faster video-on-demand, for example).
