Journal ArticleDOI
Photorefractive multiple quantum wells at 1064 nm.
Satoshi Iwamoto,S. Taketomi,H. Kageshima,Masao Nishioka,Takao Someya,Y. Arakawa,Katsuyuki Fukutani,Tsutomu Shimura,Kazuo Kuroda +8 more
TL;DR: This work fabricated photorefractive InGaAs/GaAs multiple quantum wells that are sensitive at wavelengths near 1.06 mum for what is believed to be the first time and measured four-wave-mixing diffraction efficiency, using a Nd:YAG laser.
Journal ArticleDOI
Ground state lasing at 1.30 µm from InAs/GaAs quantum dot lasers grown by metal–organic chemical vapor deposition
Denis Guimard,M. Ishida,Damien Bordel,Lin Li,Masao Nishioka,Yu Tanaka,Mitsuru Ekawa,Hisao Sudo,Tsuyoshi Yamamoto,Hayato Kondo,Mitsuru Sugawara,Yasuhiko Arakawa +11 more
TL;DR: The onset temperature at which both the peak linewidth and the PL intensity degraded and the blueshift of the ground state emission wavelength occurred was found to depend on both the QD density and the capping layer, which is particularly important in view of QD integration in photonic devices.
Journal ArticleDOI
Optimizing the GaAs capping layer growth of 1.3 μm InAs/GaAs quantum dots by a combined two-temperature and annealing process at low temperatures
TL;DR: In this paper, a combined two-temperature and annealing process at low temperatures using metalorganic chemical vapor deposition was used to optimize the GaAs capping layer growth of 1.3 mu m InAs quantum dots.
Journal ArticleDOI
Growth of InAs/GaAs quantum dots on Si, Ge/Si and germanium-on-insulator-on-silicon (GeOI) substrates emitting in the 1.3 μm band for silicon photonics
Mohan Rajesh,Damien Bordel,Kenichi Kawaguchi,Stephane Faure,Masao Nishioka,Emmanuel Augendre,Laurent Clavelier,Denis Guimard,Yasuhiko Arakawa +8 more
TL;DR: In this paper, self-assembled InAs/GaAs quantum dots (QDs) were grown on Si, Ge/Si and GeOI substrates by metal organic chemical vapor deposition.
Journal ArticleDOI
Resonant photorefractive effect in InGaAs/GaAs multiple quantum wells.
Satoshi Iwamoto,H. Kageshima,T. Yuasa,Masao Nishioka,Takao Someya,Yasuhiko Arakawa,Katsuyuki Fukutani,Tsutomu Shimura,Kazuo Kuroda +8 more
TL;DR: A large photorefractive effect caused by the excitonic electro-optic effect is observed in semi-insulating InGaAs/GaAs multiple quantum wells fabricated by metal-organic vapor-phase epitaxy and proton implantation.
