| abstract |
The invention relates to a polymeric waveguide comprising a lanthanide ion-sensitizer complex, characterized in that the lanthanide ion is preferably neodymium(III) ion (Nd 3+ ), ytterbium(III) ion (Yb 3+ ), or erbium(III) ion (Er 3+ ), and the sensitizer absorbs in the 400-1200 nm region, and preferably in the 600-1000 nm region. The invention also relates to an optical device comprising the same. |
