| Outline of Final Research Achievements |
Under the support of the KAKENHI fund, we have studied advanced Raman spectroscopic techniques and on-chip optoelectronic integrated devices based on group-IV materials. On the one hand, we demonstrated enhanced Raman spectroscopy and enhanced Raman optical activity based on the porous carbon nanowire array and silicon nanodisk array substrates, respectively. On the other hand, we have designed and developed novel graphene-on-silicon waveguide devices for various applications in light polarization control, electro-optical modulation, and biochemical sensing. Based on the previous results, we have published eleven journal papers in Nature Communications, ACS Photonics, Optics Express, IEEE Photonics Journal, Applied Physics Express, and so forth, as well as presented seven invited talks and eight oral speeches in conferences.
