Optical properties in well and barrier single-mode Nd:YLiF4 waveguides formed under 300 keV H-ion irradiation
A “well+barrier”-type, single-mode optical waveguide structure was created in a Nd:YLiF4 (Nd:YLF) crystal through H-ion irradiation at an energy level of 300 keV and a fluence of 5.6 × 1016 ions/cm2. The electronic energy loss (Se) and nuclear energy loss (Sn) induced by inelastic and elastic collisions, respectively, were simulated using the SRIM 2013 software. The cross-sectional image of the Nd:YLF crystal after H-ion irradiation was captured using a microscope. The prism coupling and end-face coupling methods were utilized to capture the effective refractive index of waveguide modes and near-field intensity distributions. The spectral characteristics of the Nd:YLF crystal were examined after H-ion irradiation based on absorption spectra and Raman spectra. This study is of considerable significance for the advancement of integrated optical devices utilizing Nd:YLF crystals.
期刊介绍：
Surface and Coatings Technology is an international archival journal publishing scientific papers on significant developments in surface and interface engineering to modify and improve the surface properties of materials for protection in demanding contact conditions or aggressive environments, or for enhanced functional performance. Contributions range from original scientific articles concerned with fundamental and applied aspects of research or direct applications of metallic, inorganic, organic and composite coatings, to invited reviews of current technology in specific areas. Papers submitted to this journal are expected to be in line with the following aspects in processes, and properties/performance:
A. Processes: Physical and chemical vapour deposition techniques, thermal and plasma spraying, surface modification by directed energy techniques such as ion, electron and laser beams, thermo-chemical treatment, wet chemical and electrochemical processes such as plating, sol-gel coating, anodization, plasma electrolytic oxidation, etc., but excluding painting.
B. Properties/performance: friction performance, wear resistance (e.g., abrasion, erosion, fretting, etc), corrosion and oxidation resistance, thermal protection, diffusion resistance, hydrophilicity/hydrophobicity, and properties relevant to smart materials behaviour and enhanced multifunctional performance for environmental, energy and medical applications, but excluding device aspects.
