Ultra‐Efficient 0.1 V cm Lithium Niobate Modulator with >$\gt$ 200 GHz Bandwidth Using a High‐Permittivity Bragg Waveguide

open access: yesAdvanced Photonics Research, Volume 7, Issue 3, March 2026.
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 ...
