| ABSTRACT |
|
In this research, the fabrication of Si/SiO$_2$optical waveguide amplifier by FHD(Flame Hydrolysis Deposition) and Solution Doping was carried out. It was observed that the reduction of fluorescence was prevented up to 0.14 wt% Er whn 0.48 wt% Al was doped and the FWHA of $1.5mutextrm{m}$ fluorescence band increased by 5 nm as increasing amount of Al. Therefore from these results, we could confirm depressing concentration quenching of Er ions and increasing FWHM of fluorescence spectrum by addition of Al. |
