Bismuth-Doped Phosphate Glasses and H+-Implanted Waveguides
Jie Zhang,Jing-Yi Chen,Chun-Xiao Liu,Liao-Lin Zhang,She-Bao Lin 한국물리학회 2020 THE JOURNAL OF THE KOREAN PHYSICAL SOCIETY Vol.76 No.6
The work reports on the preparation and optical characterization of 75P2O5-15B2O3-9Al2O3-Bi2O3 glass by using the melt-quenching method and absorption spectroscopy, respectively. Further, 0.4-MeV proton implantation of a fluence of 8.0 × 10^{16} ions/cm^2 was carried out on this glassy sample and it was tested as a waveguide at a wavelength of 632.8 nm for the first time to our knowledge. The m-line curves of the waveguide were measured before and after successive annealing treatments. The formation theory of the planar waveguides is discussed through simulations of the energy loss distribution and analysis of the reconstructed refractive index profile. The results should be useful in the design and fabrication of bismuth-doped phosphate glass and its use in integrated photonics devices.

Optical Properties of K9 Glass Waveguides Fabricated by Using Carbon-Ion Implantation
Chun-Xiao Liu,Wei Wei,Li-Li Fu,Xu-Feng Zhu,Hai-Tao Guo,Wei-Nan Li,She-Bao Lin 한국물리학회 2016 THE JOURNAL OF THE KOREAN PHYSICAL SOCIETY Vol.69 No.2
K9 glass is a material with promising properties that make it attractive for optical devices. Ion implantation is a powerful technique to form waveguides with controllable depth and refractive index profile. In this work, optical planar waveguide structures were fabricated in K9 glasses by using 6.0-MeV C3+-ion implantation with a fluence of 1.0 × 1015 ions/cm2. The effective refractive indices of the guided modes were measured by using a prism-coupling system. The refractive index change in the ion-irradiated region was simulated by using the intensity calculation method. The modal intensity profile of the waveguide was calculated and measured by using the finite difference beam propagation method and the end-face coupling technique, respectively. The transmission spectra before and after the implantation showed that the main absorption band was not influenced by the low fluence dopants. The optical properties of the carbon-implanted K9 glass waveguides show promise for use as integrated photonic devices.
