Abstract

We present a compact electro-optic (EO) modulator design exploiting the strong Pockels effect of Barium Titanate (BaTiO3 or BTO). This proposed structure, using parallel-plate electrodes tightly sandwiching the EO media, could achieve V[Formula: see text]L value as low as 35[Formula: see text]V[Formula: see text]m, a significant reduction from current photonic-integrated Pockels EO modulators with V[Formula: see text]L value around 1[Formula: see text]V⋅cm. Compared to plasmonic EO modulators, this proposed structure offers much lower optical loss. The small footprint and low-loss properties of this modulator design allow for its future embodiment in photonic-integrated CMOS circuits.

设计基于 BTO 的紧凑型电光调制器

我们提出了一种利用钛酸钡（BaTiO3 或 BTO）的强波克尔斯效应的紧凑型电光（EO）调制器设计。这种利用平行板电极紧紧夹住环氧乙烷介质的结构可实现低至 35[式：见正文]V[式：见正文]m 的 V[式：见正文]L 值，与目前 V[式：见正文]L 值约为 1[式：见正文]V⋅cm的光子集成波克尔斯环氧乙烷调制器相比，V[式：见正文]L 值显著降低。与等离子环氧乙烷调制器相比，这种拟议结构的光损耗要低得多。这种调制器设计的小尺寸和低损耗特性使其未来能够应用于光子集成 CMOS 电路。

期刊介绍： Launched in 1990, the International Journal of High Speed Electronics and Systems (IJHSES) has served graduate students and those in R&D, managerial and marketing positions by giving state-of-the-art data, and the latest research trends. Its main charter is to promote engineering education by advancing interdisciplinary science between electronics and systems and to explore high speed technology in photonics and electronics. IJHSES, a quarterly journal, continues to feature a broad coverage of topics relating to high speed or high performance devices, circuits and systems.
