Modifying the radiative quantum efficiency of erbium-doped glass in silicon slot waveguides
We have modulated the radiative emission rate of Er In SI slot waveguides with Er-doped glass slots by varying the waveguide layer dimensions. The corresponding quantum efficiency of 1537-nm emission varies between 0.37 and 0.51.
