Biodegradable Adhesive Systems for Bio‐Integrated Applications

Advanced Science, EarlyView.
Biodegradable adhesives provide temporary yet reliable adhesion while degrading into safe, non‐toxic by‐products under physiological or environmental conditions. This review summarizes recent developments in physical and chemical adhesion mechanisms—including hydrogen bonding, catechol chemistry, amine‐carboxyl coupling, and emerging diazirine and urea

SVM-Assisted Realization and Demonstration of Indoor 4 Mb/s Non-Line-of-Sight Visible Light Communication With Second-Order Reflection

IEEE Photonics Journal, 2019
Non-line of sight (NLOS) visible light communication (VLC) from reflections can expand the application of VLC beyond the line-of-sight (LOS) link. We demonstrate the experimental results on such indoor NLOS VLC, up to the second-order reflection.

Super‐Robust Telecommunications Enabled by Topological Half‐Supermodes

Advanced Science, EarlyView.
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.

Multi‐Dimensional Acoustic Cascaded Holographic Encryption with Instantaneous Visual Decryption via Particle Manipulation

Advanced Science, EarlyView.
Acoustic holograms act as key tools for information encryption, yet current schemes limit encryption dimensionality/security and require time‐consuming decryption. A compact device integrates multi‐dimensional cascaded acoustic holography with particle manipulation, employs extra secret keys, enables rapid decryption, and is validated via 1D/2D/3D ...

Semiconductor optical amplifiers for underwater optical wireless communications

IET Optoelectronics, 2017
Underwater optical wireless communications (UOWC) systems have recently received significant attention as an attractive solution for both research and commercial use because of their ability to provide high bandwidth communications over relatively short transmission spans along with their low operational cost. However, high absorption and scattering of
