Controlled modification of erbium lifetime in silicon dioxide film with chromium or titanium coatings

We report systematic measurements of the lifetime of the 1.54 μm transition of erbium implanted at different energies in SiCO 2 films coated with titanium or chromium. The lifetime shows a strong reduction up to a factor of 20 with decreasing distance between the erbium and the metal coating. Our experiments combined with rigorous theoretical modeling demonstrate that a high degree of control over the radiative properties of erbium can be achieved in erbium-irnplanted materials. © 2008 Materials Research Society.
