Review of Coherent Anti‐Stokes Raman Scattering Nonresonant Background Removal and Phase Retrieval Approaches: From Experimental Methods to Deep Learning Algorithms

open access: yesAdvanced Photonics Research, EarlyView.
Coherent anti‐stokes Raman spectroscopy (CARS) enables high‐resolution vibrational imaging, yet non‐resonant background (NRB) distorts spectral fidelity. This review highlights NRB removal methods—from experimental strategies and numerical algorithms to emerging deep learning techniques.

Pressure‐Assisted Ceramic Processing of Metal Halide Perovskites

open access: yesAdvanced Photonics Research, EarlyView.
This review critically assesses low‐temperature, pressure‐assisted ceramic processing as a pivotal technique to fabricate dense, polycrystalline wafers with precisely controlled macroscopic dimensions as well as microstructural properties. The aim is to bridge understanding between expert ceramists and halide perovskite specialists, highlighting the ...

Thermal Shrinkage‐Induced Modifications in Photonic Bandgaps of Two‐Photon Polymerized Bragg Reflectors

open access: yesAdvanced Photonics Research, EarlyView.
Scanning electron microscopy and white‐light reflectance images of the pillar‐supported distributed Bragg reflector (DBR) are presented before and after thermal shrinkage. The DBR, fabricated via two‐photon polymerization, consists of alternating high‐ and low‐index layers supported by vertical pillars.

Non‐Hermitian Topological Lattice Photonics: An Analytic Perspective

open access: yesAdvanced Photonics Research, EarlyView.
This review establishes exact analytical solutions for non‐Hermitian Hatano–Nelson, Su–Schrieffer–Heeger, and generalized Rice–Mele models. We demonstrate non‐Hermitian skin effects via point‐gap topology, hybrid skin‐topological edge states in 2D lattices, and spin‐polarized boundary modes governed by dual bulk‐boundary correspondence.

Topological Berry Antenna on a Silicon Chip for Terahertz Wireless Communication

open access: yesAdvanced Photonics Research, EarlyView.
The on‐chip topological Berry antenna for 6G to Xth‐generation wireless communication is designed via integrating various Berry curvatures for an enhanced antenna aperture and radiation gain. This THz antenna has demonstrated a maximum gain of 17 dBi and chip‐to‐chip wireless communications at 20 Gbps over a distance of 15 cm.
