| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | Waveguide propagation losses ($\lambda$:1.55$\mu$m) in Si nanocrystals and Er codoped $SiO_2$ films were measured with various doping concentrations for an application to a waveguide amplifier. Photoluminescence intensity by Er ions was measured to be higher by increasing the Si concentration, and lower by increasing it further. Without excitation to a waveguide, the waveguide loss was increased by increasing the Si concentration. It is important that the Si nanocrystals should be evaluated as a cause of a loss as well as a sensitizer for the amplifier. Propagation losses were also measured by changing both the Er and Si concentrations. It is important to optimize both the Si and Er concentrations, based on the results of those loss values. | |
