We report on the construction of wave guiding structures operating at 632.8 nm in the Yb3+-doped phosphate glass by two different techniques: carbon-ion implantation with a single-implant at an energy of 6.0 MeV and a dose of 5.0 x 10(14) ions cm(-2), and proton implantation with a double-implant of energies of (500 vertical bar 550) keV and doses of (1 vertical bar 2) x 10(16) ions cm(-2). The annealing treatments were performed at different temperatures ranging from 260 degrees C to 460 degrees C at internals of 50 degrees C. For the proton-implanted waveguide, the m-line spectrum and the refractive index profile were studied by a modal 2010 prism coupler and a reflectivity calculation method, respectively. The near field patterns in the both cases were recoded by an end-fire coupling system. The carbon-and proton-implanted Yb3+-doped phosphate glass waveguides can propagate guided modes after the continuous annealing, suggesting the applicability in the development of photonics devices.
