Optical and magnetic properties in well and barrier ZnS waveguides formed by MeV Ni and Cu ion implantation
Optical Materials(2023)
摘要
Well and barrier waveguides were fabricated in zinc sulfide (ZnS) single crystals via nickel (Ni) and copper (Cu) ion implantation. Elastic collisions between the implanted ions and target nuclei were reconstructed using SRIM software. The prism coupling and end-face coupling methods were applied to capture the dark-mode spectrum and near-field intensity distributions, respectively, at 633 nm. The absorption spectra from the UV to visible band of the ZnS crystals before and after Ni and Cu ion implantation were collected on a spectrophotometer. Magnetic properties at room temperature were evaluated under a magnetic field of 3T.
