Planar waveguides produced by implanting Si and C ions in rutile

Julián Mejía Morales, Erick Flores-Romero, Rebeca Trejo Luna, Jorge Rickards


Planar waveguides were generated in samples of rutile crystal (TiO2) by bombarding with two types
of ion: silicon and carbon. Rutile is used because of its anisotropic properties, particularly its birefrin-
gence. The guide is generated due to damage caused by the ions in the crystal which change its index of
refraction. Three parameters were used: the implantation ion energy, the implantation
uence, and the
orientation of the crystallographic planes. The refractive index prole of the irradiated sample was cal-
culated and together with the value of the optical barrier the comparison was made between the dierent
waveguides generated.
