Quantum-dot single-photon source on a CMOS silicon photonic chip integrated using transfer printing
Ryota Katsumi, Yasutomo Ota, Alto Osada +6
Silicon photonics is a powerful platform for implementing large-scale photonic integrated circuits (PICs), because of its compatibility with mature complementary-metal-oxide-semico…
Photonic crystal nanocavity based on a topological corner state
Yasutomo Ota, Feng Liu, Ryota Katsumi +4
Topological phonics has emerged as a novel approach to engineer the flow of light and provides unprecedented means for developing diverse photonic elements, including robust optica…
Strongly coupled single quantum dot-cavity system integrated on a CMOS-processed silicon photonic chip
Alto Osada, Yasutomo Ota, Ryota Katsumi +3
Quantum photonic integrated circuit (QPIC) is a promising tool for constructing integrated devices for quantum technology applications. In the optical regime, silicon photonics emp…
Topological photonic crystal nanocavity laser
Yasutomo Ota, Ryota Katsumi, Katsuyuki Watanabe +2
Topological edge states exist at the interfaces between two topologically-distinct materials. The presence and number of such modes are deterministically predicted from the bulk-ba…
Transfer-printed quantum-dot nanolasers on a silicon photonic circuit
A. Osada, Y. Ota, R. Katsumi +3
Quantum-dot (QD) nanolasers integrated on a silicon photonic circuit are demonstrated for the first time. QD nanolasers based on one-dimensional photonic crystal nanocavities conta…
Transfer-printed single photon sources coupled to wire waveguides
Ryota Katsumi, Yasutomo Ota, Masahiro Kakuda +2
Photonic integrated circuits (PICs) are attractive platforms to perform large-scale quantum information processing. While highly-functional PICs (e.g. silicon based photonic-circui…
