| Outline of Final Research Achievements |
In this study, we fabricated a polymer hybrid modulator using silicon waveguide, which consists of a traveling wave type electrode for highly efficient optical signal generation. The measured results of the modulation demonstrated symbol rate of 100 Gbaud and signal transmission of 200 Gbit/s. In experiments of the optical signal transmission, the signal error rate was analyzed as below the error-free accuracy, and it was confirmed that the signal transmission did not degrade even when subjected to temperature up to 110°C. As the goal of this research, a high-speed optical modulation device was fabricated and its highly efficient optical modulation performance was demonstrated.
