Abstract
KNbO3 thin epitaxial films were sputter deposited onto (100) oriented spinel and MgO substrates. Waveguiding with losses as low as 1.1 dB/cm at λ=632.8 nm was achieved. The nonlinear optical coefficient d31=6.3 pm/V was determined by a Maker Fringe measurement using the 1.06 µm Nd:YAG laser fundamental wavelength.
