With the advancements in electron microscopy, the spectroscopic techniques based on electron beam are widely used to get the photonic information of nanophotonic structures such as photonic crystals, metamaterials, and plasmonic nanostructures. In so doing, free electrons provide unique opportunities in pumping or probing such nanostructures with their unrivalled broadband and localized excitation capability compared to ordinary light illumination. Apart from spectroscopy, those capabilities can also enable the efficient pumping of nanophotonic structures for the generation of light in various forms. Here, we will discuss our recent efforts to pump various nanophotonic structures toward the development of nanoscale light sources [1,2]. The concept of amplifying the evanescent field of free electrons will also be discussed where it is enabled by introducing a plasmonic metal film [3] in a fiber-based geometry.

Abstract

With the advancements in electron microscopy, the spectroscopic techniques based on electron beam are widely used to get the photonic information of nanophotonic structures such as photonic crystals, metamaterials, and plasmonic nanostructures. In so doing, free electrons provide unique opportunities in pumping or probing such nanostructures with their unrivalled broadband and localized excitation capability compared to ordinary light illumination. Apart from spectroscopy, those capabilities can also enable the efficient pumping of nanophotonic structures for the generation of light in various forms. Here, we will discuss our recent efforts to pump various nanophotonic structures toward the development of nanoscale light sources [1,2]. The concept of amplifying the evanescent field of free electrons will also be discussed where it is enabled by introducing a plasmonic metal film [3] in a fiber-based geometry.
