We present the optical properties such as the linear refractive index (n), the absorption coefficient (α), the energy band gap (Eg) and the nonlinear refractive index (n2) measured by spectroscopy and degenerate four wave mixing methods for Er3+-doped oxyfluoride glasses and nano-glass-ceramics.The n2 of the Er3+-doped oxyfluoride nano-glass-ceramic is almost twice that of the Er3+-doped parent oxyfluoride...
We present linear (n) and nonlinear (n2) refractive indices, linear absorption coefficient (α), optical conductivity (σ) and 3rd order nonlinear optical susceptibility (χ<;3>) of glasses: 32(SiO2):9(AlO1.5):31.5(CdF2):18.5(PbF2): 5.5(ZnF2):3.5(RE-F3)mol% (RE: Er3+ or Yb3+). Measurement techniques used are spectroscopic ellipsometry, nonlinear transmission and degenerate four wave mixing. It...
Femtosecond-pulsed laser writing of waveguides, a few mm long, is demonstrated; waveguides were written orthogonally to the writing beam inside the bulk of ErIII-doped oxyfluoride glasses at a depth of 160 mum. The writing beam was 795 nm wavelength, 54 fs pulse duration and 11 MHz repetition rate. Tracks were written at pulse energies of 13.1 nJ to 26.1 nJ and sample translational velocity of 10...
