Varnish containing optical doping material and optical waveguide amplifier using the same |
| abstract |
An object of the present invention is to provide a fluorinated polyimide precursor varnish to which a rare earth metal is added at a high concentration, and an optical waveguide amplifier using the varnish. A light doping material obtained by mixing a complex obtained by reacting a rare earth metal salt and a metal alkoxide, and a carboxylic acid compound in an organic solvent, and a fluorinated polyimide precursor. varnish.
