Periodic Domain Inversion in Single Crystal Barium Titanate‐on‐Insulator Thin Film

Periodic Domain Inversion in Single Crystal Barium Titanate‐on‐Insulator Thin Film

Abstract Experimentally achieving the first‐ever electric field periodic poling of single crystal barium titanate oxide (BTO, or BaTiO3) thin film on‐insulator is reported. Owing to the outstanding optical nonlinearities of BTO, this result is a key step toward achieving quasi‐phase‐matching (QPM)....
