Er/sup 3+/ absorption cross section in Si-nanocrystal waveguides in SiO/sub 2/

摘要

This paper reports on Er/sup 3+/ absorption cross section measurement by transmission measurements in waveguide /spl sigma//sub abs/ measured value is 0.5-1.7 /spl times/ cm at 1534 nm for all samples resulting very close to that of Er/sup 3+/ in pure silica.
