Spatially‐Controlled Planar Guided Crystallization of Low‐Loss Phase Change Materials for Programmable Photonics

Advanced Materials, EarlyView.
The concept of spatially‐controlled planar guided crystallization is a novel method for programming the growth of optically homogeneous low‐loss Sb2S3 phase‐change material (PCM), leveraging the directional crystallization within confined channels.

A Versatile Materials Class for Solution‐Processed Optics and Photonics Based On Titanium Oxide Hydrates and Polyalcohols: A Perspective

Advanced Materials, EarlyView.
A new, solution‐processable class of optical materials based on molecular hybrids of metal oxide hydrates and commodity polymers is discussed here, including their synthesis, processing into thin films, patterning, and photonic structures realized to date.

Emergent Berry Curvature in Inversion‐Symmetric Photonic Crystals for Ultraconfined Topological States

Advanced Materials, EarlyView.
In this work, nonzero Berry curvature in photonic crystals is induced by breaking unit cell inversion symmetry through spatial shifts rather than geometrical modifications. This enables the design of ultraconfined topological states with subwavelength in‐plane field confinement and out‐of‐plane field isolation.

Propagation thermoelastic impulse through a cylindrical waveguide under sidewall heat interchanging

Vestnik Samarskogo Gosudarstvennogo Tehničeskogo Universiteta. Seriâ: Fiziko-Matematičeskie Nauki, 2011
The paper is devoted to a study of coupled harmonic thermoelastic impulse guided propagation through an infinite circular cylinder. Heat interchanging is supposed to take place between sidewall of the waveguide and environment.
