Abstract

Light sources are ubiquitous in our lives. Common light sources include sunlight and incandescent lamps, which emit visible spectrum to help us to see surrounding objects via blackbody radiation. Further understanding and control on the quanta of light, called photons, have led to numerous advances in nanophotonics and related research fields, but recently their impact has been most notable in quantum computing, com-munications, biosensing, and imaging technology. Most of these applications have been made possible through the development of ultrasmall and ultrafast light sources based on advanced nanotechnology. In this review, we aim to give a clear picture of the historical achievements regarding light sources and how recent studies have developed the field of ultrasmall light sources, especially in relation to quantum electron tunneling mechanisms. Finally, we discuss the potential applications for emerging quantum devices and sensing technologies.
