| Outline of Final Research Achievements |
To adapt the increase of the bandwidth for future photonic networks, it is expected to realize direct modulated lasers which have faster modulation bandwidth beyond conventional semiconductor lasers.
First, by theoretical discussion, design guidelines to reduce the parasitic capacitance of transistor lasers, which were a big issue for conventional transistor lasers, were established. And in actual fabrication, better static characteristics and dynamic characteristics, which agreed with the theoretical calculation, were demonstrated. Therefore, this proved the effectiveness of the theoretical discussion in this project.
Because of these results, outlook and ways to realize transistor lasers with enough performances for future high speed network are shown.
