摘要：
We present a compact electro-optic (EO) modulator design exploiting the strong Pockels effect of Barium Titanate (BaTiO3 or BTO). This proposed structure, using parallelplate electrodes tightly sandwiching the EO media, could achieve VπL value as low as 35V·μm, a significant reduction from current photonic-integrated Pockels EO modulators with VπL value around 1V·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. © 2024 World Scientific Publishing Company.
