This work demonstrates thin‐film lithium niobate Mach–Zehnder modulators. One of these modulators achieves a voltage‐length product of 0.1 V cm, a driving voltage of 1 V, a device length of 1 mm, and a bandwidth exceeding 200 GHz. A high‐permittivity cladded Bragg grating waveguide is utilized to enhance modulation efficiency, enabling low‐voltage and ...

Observation of Edge‐Confined Acoustic Hyperbolic Polaritons in van der Waals Materials
This work demonstrates a new type of light wave—edge‐confined acoustic hyperbolic polaritons—in hexagonal boron nitride on gold. These waves travel along crystal edges with nanoscale confinement and strongly interact with molecular vibrations, enabling highly sensitive detection of tiny molecular layers.

We demonstrate a hybrid WS2/CuInP2S6/graphene heterostructure integrated on a silicon nitride microring resonator for non‐volatile optical phase modulation with ultra‐low energy consumption and low insertion loss. While CIPS alone does not provide efficient optical index modulation, the engineered proposed device structure converts ferroelctric domain ...

Au nanobipyramids (Au NBPs) with distinct Pt configurations—dense Pt layers (Au NBPs@Ptd), sparse Pt clusters (Au NBPs@Pts), and trace AuPt alloy (Au NBPs@Au/Ptalloy) were engineered. Au NBPs@Au/Ptalloy exhibited optimal performance in the photoelectrocatalytic nitrite‐to‐ammonia conversion.

Molecular fingerprinting for the detection of biomolecules is highly sensitive and noninvasive through the surface‐enhanced Raman scattering (SERS) effect. This is a report on the commercially competitive performance of gold‐coated periodic structures and black Si (aperiodic) nanostructures as plasmonic SERS substrates.
