Revealing low-loss dielectric near-field modes of hexagonal boron nitride by photoemission electron microscopy
Abstract Low-loss dielectric modes are important features and functional bases of fundamental optical components in on-chip optical devices. However, dielectric near-field modes are challenging to reveal with high spatiotemporal resolution and fast direct imaging. Herein, we present a method to addr...
