| 研究実績の概要 |
I have experimentally demonstrated a mid-infrared germanium nanocavity with a Q factor of 18,000, the highest-to-date of reported nanocavities across mid-infrared germanium-based integration platforms. This work is published in Photonics Research and listed as one of the top downloads in September 2018. Based on this result, I also has given two invited talks and four oral presentations in international conferences.

1: 当初の計画以上に進展している
理由
In Phase I of the project, I have developed a novel mid-infrared germanium photonics integrated circuits for sensing applications. During this phase, all fabrication processes of mid-infrared photonic devices have been developed and optimized. Now, I am working on the fabrication of graphene-silicon photonic-plasmonic hybrid integrated circuits. Moreover, I have purchased all the necessary components in Phase I and am building up a setup for gas sensing applications. The budget is enough for my experiments.

| 今後の研究の推進方策 |
In Phase II of the project, I am planning to carry out my study in two aspects:
(1)Work on the graphene-silicon photonic-plasmonic hybrid integrated circuits.
I plan to demonstrate the proposed graphene-silicon photonic-plasmonic hybrid integrated circuits. Localized surface plasmonic resonance in graphene will be excited and measured via in-plane light-matter interactions.
(2)Work on an experimental setup for gas sensing applications.
I plan to finish the experimental setup for gas sensing applications. On-chip absorption spectroscopy could be measured based on this setup.
