A KAIST-led research team has characterized how light propagates through and is absorbed by barium titanate (BTO), a promising material for next-generation optical communication devices. By clarifying optical properties that had been difficult to determine because of the material\u2019s complex internal structure, the study provides a foundation for designing these devices.<\/p>\n
The research team led by professor Min Seok Jang of its School of Electrical Engineering had precisely characterized BTO\u2019s refractive index and absorption properties across wavelengths ranging from the ultraviolet to the far-infrared. The study was conducted in collaboration with professor Harry A. Atwater\u2019s team at the California Institute of Technology (Caltech), the Korea Research Institute of Standards and Science (KRISS) and U.S.-based J.A. Woollam Co. The work is published<\/a> in ACS Photonics.<\/p>\n BTO\u2019s refractive index changes when an electric field is applied. Its strong electro-optic response, known as the Pockels effect, makes it a promising material for optical modulators, which encode information from electrical signals onto light.<\/p>\n","protected":false},"excerpt":{"rendered":" A KAIST-led research team has characterized how light propagates through and is absorbed by barium titanate (BTO), a promising material for next-generation optical communication devices.
