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…
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…
Optical coupling between atomically-thin black phosphorus and a two dimensional photonic crystal nanocavity
Yasutomo Ota, Rai Moriya, Naoto Yabuki +5
Atomically-thin black phosphorus (BP) is an emerging two dimensional (2D) material exhibiting bright photoluminescence in the near infrared. Coupling its radiation to photonic nano…
Time-resolved vacuum Rabi oscillations in a quantum dot-nanocavity system
K. Kuruma, Y. Ota, M. Kakuda +2
We report time-domain observation of vacuum Rabi oscillations in a single quantum dot strongly coupled to a nanocavity under incoherent optical carrier injection. We realize a phot…
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…
