Planar Waveguides in γ-LiAlO2 With Ion Implantation: Light Being Facilely Propagated

The investigation on the terbium gallium garnet (TGG) crystal waveguides in the visible and near-infrared bands is significant for potential applications in science and technology. In this work, we report on a TGG planar waveguide based on the proton irradiation with an energy of 400 keV and a dose of [Formula: see text] ions/cm2. The annealing treatments are adopted to improve optical performances of the waveguide on the conditions of 260[Formula: see text]C and 410[Formula: see text]C severally for 1 h. The dark-mode spectra and the refractive index distributions of the TGG waveguide are obtained before and after the thermal treatments. There is a strange phenomenon that nine modes are observed on the m-line curve after the annealing treatment at 410[Formula: see text]C. The theoretical and experimental results demonstrate that the fabricated waveguide annealed at the temperature of 410[Formula: see text]C can propagate more guided modes and have better capacity to confine light.

In this work, we report on the preparation and characterization of the planar and ridge optical waveguides in the E r 3 + -doped germanate glass by combining hydrogen ion implantation and precise diamond blade dicing. The nuclear energy loss and the implantation depth were calculated by the SRIM 2013 software. The refractive index profile was obtained by the reflectivity calculation method. The dark-mode spectrum and the near-field intensity distribution were measured by the prism coupling system and end-face coupling technique, respectively. This work has important reference significance for the development of E r 3 + -doped germanate glass active devices in the optical communication field.
