Tóm tắt

Electro-optical (EO) modulators with lithium niobate waveguide are essential components in modern communication systems and quantum photonic applications. With the advancement of cryogenic photonic integrated circuits, they have become critical for cryogenic photonic readout, enabling massive data transfer from superconducting electronics to room temperature environments. Here, we demonstrate an integrated modulator based on a thin-film lithium niobate platform. The designed modulator achieves a tuning efficiency (
