Advanced Photonics Research, Volume 7, Issue 10, October 2026.In this work, thin‐film lithium niobate Mach–Zehnder modulators are realized using codesigned slow‐light optical waveguides and inductively loaded RF electrodes. This dual slow‐wave engineering optimizes velocity matching, achieving Vπ·L = 0.3 V cm, bandwidths up to 200 GHz, Vπ ≤ 1 V, and short device lengths, offering an efficient solution for high ...

High‐Efficiency Graphene‐Silicon Slot‐Waveguide Microring Modulator at 1.5 and 2 µm Wavelength Bands
Laser &Photonics Reviews, Volume 20, Issue 19, 7 October 2026.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.
