Nonlinear measurement of mid-infrared absorption in AlO[sub x] waveguides
M. Ravaro, E. Guillotel, M. Le Du, C. Manquest, X. Marcadet et al.
We report a quantitative study on the absorption of oxidized-AlAs (AlO) integrated thin layers in the mid-infrared range (24 [mu]m). An AlO absorption coefficient of 1600 cm is measured in a nonlinear waveguide, by investigating the phase-matching bandwidth of parametric fluorescence. Since mid-in ... [Appl. Phys.
