Advanced Photonics Research, Volume 7, Issue 3, March 2026.This article proposes a deep learning (DL) approach for modeling and optimizing frequency‐doubled radio‐over‐fiber links. By collectively replacing traditional components with DL model, accurate system evaluation is achieved. Moreover, through an end‐to‐end architecture, performance optimization is accomplished.

Super‐Robust Telecommunications Enabled by Topological Half‐Supermodes
Advanced Science, Volume 13, Issue 13, 3 March 2026.Through topological half‐supermode engineering, we realize a valley‐ridge gap waveguide that is directly compatible with conventional waveguides and features topological protection. This design halves the lateral size via a PEC boundary, enabling direct TE₁₀‐mode matching and robust bend‐immune transmission.

Interrogation of Voids in SOlids Utilizing Ramp Function Ultrasonic Pulses [PDF]
, 1980 From some low frequency scattering investigations in radar, it is suggested that interrogating the target with ramp function has distinct advantages. This ramp function is a ramp in amplitude, not frequency. The returning echo is predicted to exhibit
