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.
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.
