Plasmonic Metafibers Simplify Electro-Optic Modulator Integration
ZHEJIANG, China, Aug. 30, 2023 — Electro-optic modulators (EOMs) are critical elements in the optical communication networks that control the amplitude, phase, and polarization of a light via external electric signals. Aiming to realize ultracompact and high-performance EOMs, most investigations today target on-chip devices that combine semiconductor technologies with state-of-art tunable materials. Nevertheless, integrated EOMs, as an independent on-chip element, are commonly separated from light sources. Accordingly,
