We improved the dry-etching process for Nb 2 O 5 horizontal slot waveguides to suppress roughness in etched surfaces. We have also fabricated horizontal slot waveguides by the improved process. In the fabricated waveguides, the smooth etched surface

In order to increase the phase shift effect due to the refractive index change of the cladding, optical switches using Nb 2 O 5 core waveguides were studied. A wavelength shifting operation was obtained by the fabricated device.
