Light-matter interaction is one of the fundamental phenomena of the universe that has significantly shaped the evolution of the human society. In this talk, we present research on light-matter interactions at nanoscale, also known as "nanophotonics," for optical sensing, communication, and energy sustainability. We will discuss the fundamentals and applications of nanophotonics through a few examples. These include extending our vision beyond the visible regime by integrating X-ray/ultraviolet/infrared materials onto silicon-based image sensors, harnessing solar absorption of transition metal oxide nanoparticles towards dispatchable solar thermal electricity, and modulating photons efficiently utilizing quantum wells and 2D materials for data communication and light detection and ranging (LiDAR). Adapting Feynman’s famous quote envisioning the advent of nanotechnologies, we show that not only is there "plenty of room at the bottom," but plenty of room to "light up" the bottom as well.
