Imaging Photonic Resonances within an All‐Dielectric Metasurface via Photoelectron Emission Microscopy

open access: yesAdvanced Photonics Research, EarlyView.
Photonic resonances within a dielectric metasurface are investigated using photoelectron emission microscopy (PEEM) and finite‐difference time‐domain simulations. An electron inelastic mean free path of 35 ± 10 nm is extracted from comparisons between microscopy and simulations.

Precision Construction of Chiral Optical Fields with Nine Controllable Degrees of Freedom

open access: yesAdvanced Photonics Research, EarlyView.
Chiral optical fields (COFs) offer multiple controllable degrees of freedom (DOFs), enabling applications in optical tweezers, manufacturing, and encryption. However, achieving precise sidelobe control remains a challenge. This work introduces a modular multilayer annular phase plate to fine‐tune COFs by manipulating nine DOFs.
