Abstract

A titanium-doped gallium lanthanum oxysulfide glass waveguide was fabricated by double proton implantation. The waveguide does not exhibit tunneling effect, which is consistent with our design. The refractive index distribution of the waveguide was reconstructed, and the propagation loss was measured to be $0.5\mathrm{dB}/\mathrm{cm}$, caused by the ion implantation. Based on Raman analyses, we conclude that the glass matrix expansion due to nuclear damage causes optical barrier formation. Little change in the guiding layer and low propagation loss present that a Ti-doped chalcogenide glass waveguide may be a candidate for tunable lasers and has the possibility of taking the place of versatile but expensive Ti:sapphire lasers.
