The three spectroscopic parameters of Dy:LPS were calculated using the Judd-Ofelt theory, and a planar waveguide was fabricated on Dy:LPS by proton implantation. The dark-mode spectrum was obtained using the prism coupling method, and the refractive index profile of the waveguide structure was reconstructed using RCM. The mode profile of the waveguide was investigated using the end-face coupling technique. The study suggests that Dy:LPS crystal and its waveguide structure have potential applications in integrated optics, especially in the fabrication of solid-state waveguide lasers.
In this work, the three spectroscopic parameters of the Dy:LPS were calculated as follows: 2.0902 x 10(-20) cm(2), 0.2469 x 10(-20) cm(2), and 0.4597 x 10(-20) cm(2), according to the Judd-Ofelt theory. Then, a planar waveguide was fabricated on the Dy:LPS by the proton implantation with an energy of 400 keV and a dose of 8 x 10(16) ions/cm(2). The dark-mode spectrum was obtained by the prism coupling method. Correspondingly, the refractive index profile of the waveguide structure was reconstructed by the RCM. The mode profile of the waveguide was investigated by the end-face coupling technique. The results suggest that the Dy:LPS crystal and its waveguide structure have potential applications in integrated optics, especially in the fabrication of solid-state waveguide lasers.
