Contactless Terahertz “Fiber Squeezer” for Tunable Dispersion Engineering in Unclad Silicon Dielectric Waveguides

Advanced Photonics Research, Volume 7, Issue 3, March 2026.
Terahertz microscale silicon waveguides can be wholly unclad, making it possible to interact with guided waves contactlessly via evanescent fields. We exploit this with conductive walls that enforce a movable field‐null upon modal fields, enabling tunable dispersion and cutoff similar to a fiber squeezer, albeit without physical contact.

Diffractive Neural Networks for High‐Throughput Classification of Objects in Microfluidic Systems

Advanced Photonics Research, Volume 7, Issue 3, March 2026.
Imaging flow cytometry (IFC) is a powerful tool for high‐content analysis of biological specimen, although throughput of modern IFC systems is limited by camera acquisition rates and digital image processing speeds. This article proposes the use of diffractive neural networks (DNNs) for IFC and lays out a path toward simultaneous high content and high ...

Angularly Stable Terahertz Metasurface With Multi‐Frequency Narrowband Cross‐Polarization Conversion and Broadband Quarter Waveplate Function

Advanced Photonics Research, Volume 7, Issue 3, March 2026.
A compact dual‐functional reflective terahertz (THz) metasurface is experimentally demonstrated. Near‐unity linear‐to‐cross polarization conversion is achieved at four resonance frequencies: 0.65, 0.80, 2.02, and 2.48 THz. Broadband linear‐to‐circular polarization conversion is realized in two bands, 0.86–1.95 THz (77% fractional bandwith, FBW) and 2 ...
