| Research Abstract |
In this research, we have aimed to develop ultra-small plasmonic photonic integrated circuits by introducing plasmonic technologies to the compound semiconductor photonic integrated circuits. As a result, we have proposed a novel plasmonic coupler to efficiently focus and couple light into plasmonic waveguides narrower than the diffraction limit. We have successfully fabricated the device and carried out proof-of-concept experiment. Concurrently, we have analyzed nanometallic lasers and proposed a novel capsule-shaped structure to increase the cavity Q factor drastically.
