Batio Waveguides Achieve 2.75x Enhanced Nonlinear Frequency Conversion Efficiency

Researchers at the Fraunhofer Institute have introduced hybrid barium titanate‑titanium dioxide (BaTiO₃‑TiO₂) ridge waveguides that achieve a 2.75‑fold increase in normalized second‑harmonic generation (SHG) efficiency compared with monolithic BaTiO₃ devices. The design embeds a thin TiO₂ layer to reshape modal confinement, enabling strong nonlinear mode overlap through pure modal phase‑matching, eliminating the need for periodic poling. Coupled‑mode‑theory simulations guided the geometry, confirming the efficiency boost and matching lithium‑niobate performance. The fully lithographic, CMOS‑compatible process promises scalable production of high‑efficiency χ² photonic components.
