All optical integrated upconversion fluorescence-based point temperature sensing system using Er3+-doped silica-on-silicon waveguides

In this work an optically integrated and compact point temperature sensor based upon upconversion fluorescence emission in an Er3+-doped silica-on-silicon waveguide is proposed. The sensing system relies upon the temperature information residing in the intensity ratio of two thermally coupled upconv...
