Probing the Photonic Local Density of States with Electron Energy Loss Spectroscopy
Probing the Photonic Local Density of States with Electron Energy Loss Spectroscopy
Electron energy loss spectroscopy performed in transmission electron microscopes is shown to directly render the photonic local density of states with unprecedented spatial resolution, currently below the nanometer. Two special cases are discussed in detail: (i) 2D photonic structures with the electrons moving along the translational axis of symmetry and …
