Modal Theory of Phase‐Modulated and Frequency‐Shifting Ring Cavities

Advanced Photonics Research, EarlyView.
We present a theoretical and experimental characterization of the optical modes of dispersionless ring cavities with phase modulators or frequency shifters. Their response to arbitrary modulation acts as a filter for phase‐modulated modes that determine the optical output of passive resonators and lasers. This provides a general framework for analyzing

MRI Epicenters Differentiate Spatiotemporal Patterns of Neurodegeneration in Parkinson's Disease

Advanced Science, EarlyView.
A connectivity‐based MRI epicenter model identifies two Parkinson's disease subtypes: subtype 1 with infratentorial‐dominant epicenters, severe motor symptoms, and rapid progression; and subtype 2 with supratentorial‐dominant epicenters with mild progression.

Ultra‐Thin Oxide‐Based Double‐Layer Architecture Achieves Wide‐Temperature Broadband Microwave Absorption by Synergizing Lorentz Resonance and Thermionic Transport

Advanced Science, EarlyView.
Developing ultrathin wide‐temperature adaptive microwave absorption materials (MAMs) is crucial for enhancing the survival of military devices under alternating high‐temperature environment. Here, a double‐layer La2Zr2O7/Eu2Zr2O7 architecture is employed, with rare‐earth zirconates featuring with one‐eighth anion‐site vacancies, successfully achieving ...

All‐Optical Logic Gates and Programmable Photonic Organo‐Polymer Devices

Advanced Electronic Materials, EarlyView.
Four PDMS‐based photonic devices imitating the shapes of Y‐structure, hexagonal mesh, dual in‐phase quadrature, and cascaded MZI array are demonstrated and shown to function as all‐optical OR gates. Furthermore, a PDMS hexagonal mesh, containing dye‐doped regions, is shown to enable performance as a programmable photonic device, where its ...
