Highly efficient broadband second harmonic generation using polydomain epitaxial barium titanate thin film waveguides
Pao Tai Lin, B. W. Wessels, Joon I. Jang, and J. B. Ketterson
Broad band second harmonic generation (SHG) over the spectral range of 530700 nm is reported using an epitaxial barium titanate (BaTiO) thin film waveguide. The epitaxial layers are multidomain consisting of both a and c domain variants. The SHG conversion efficiency is nearly independent of wavele ... [Appl. Phys. Lett. 92, 221103 (2008)] published Mon Jun 2, 2008.
