| Abstract Scope |
Ferroelectric materials provide a powerful platform for the manipulation of light due to the strong coupling between the ferroelectric and optical properties, making them critical for emerging technologies in integrated photonics and quantum computing. However, existing computational approaches fail to resolve the full complexity of the optical properties in ferroelectric materials, particularly in the presence of ferroelectric domain structures. To solve this problem, we introduce a new computational framework that uses the phase-field method to model the optical properties of complex ferroelectric microstructures, which automatically includes the connection between the spatially varying ferroelectric polarization, strain, and optical properties. We demonstrate the capabilities of this framework through a case study of BaTiO3 thin films, enabling the analysis and design of their linear optical, electro-optical, and second harmonic generation properties. |
