High-temperature optical properties of sensitized Er3+ in Si-rich SiO2 – implications for gain performance

The high-temperature photoluminescence of Er-doped Si-rich SiO2 with and without silicon nanocrystals is studied at sample temperatures in the range 20?200?C. The optical properties of Er-doped Si-rich SiO2 with and without silicon nanocrystals are shown to exhibit a similar temperature dependence.
