Lattice structures and optical properties of Ce:LYSO crystal waveguides with implanted C, Si and Cu ions

We report on the lattice structures and optical properties of Ce:LYSO crystal waveguides implanted with C, Si and Cu ions at 6 MeV. SRIM software was used to reconstruct the elastic collisions between the implanted ions and target nuclei. The maximum structural changes were induced by the Cu-ion implantation, as determined by XRD and Raman spectra. Photoluminescent and absorption spectra were used to study the optical properties of Ce3+ ions in the Ce:LYSO waveguides. Prism-coupling and end-face coupling methods, respectively, were used to measure the guiding modes and the near-field intensity distribution of light at 633 nm. Typical well + barrier waveguides were formed in the Ce:LYSO crystals implanted by C, Si and Cu ions, which will be a interest application in integrated optical devices.
