High‐Efficiency Graphene‐Silicon Slot‐Waveguide Microring Modulator at 1.5 and 2 µm Wavelength Bands

Laser &Photonics Reviews, EarlyView.
E/O modulators typically face a trade‐off between bandwidth and modulation efficiency. An integrated E/O modulator is presented that simultaneously achieves wideband, large bandwidth, and high modulation efficiency operation by embedding a partially overlapped double‐layer graphene on a compact silicon slot‐waveguide microring resonator.

Reversible Hydration Tuning of Polar Order and Large Nonlinear Optical Response in a 2D van der Waals Crystal, LiInP2S6

Advanced Materials, Volume 38, Issue 52, 16 September 2026.
Hydration‐induced symmetry breaking transforms layered LiInP2S6${\rm LiInP}_2{\rm S}_6$ from a nonpolar to a chiral‐polar phase, producing a giant enhancement of non‐resonant second‐harmonic generation. The reversible tuning of polar order through molecular intercalation establishes a strategy for dynamically controlling nonlinear optical ...
