Damien Bonneau,Erman Engin,Kazuya Ohira,Nobuo Suzuki,Haruhiko Yoshida,Norio Iizuka,Mizunori Ezaki,Chandra M. Natarajan,Michael G. Tanner,Robert H. Hadfield,Sander N. Dorenbos,Val Zwiller,Jeremy L. O'Brien,Mark G. Thompson +13 more
TL;DR: In this article, an integrated photonic quantum technology platform utilizing the silicon-on-insulator material system was presented, where quantum interference and the manipulation of quantum states of light were demonstrated in components orders of magnitude smaller than previous implementations.
Patent
Semiconductor optical waveguide device, optical control type optical switch, and wavelength conversion device
Nobuo Suzuki,Hirayama Yuzo +1 more
TL;DR: A semiconductor optical waveguide device comprises a stripe-shaped semiconductor infrared waveguide, part of which is an active layer producing gain by electric current injection, and part of the semiconductor IR waveguide being an intra-band resonant absorption layer in which an IR resonant wavelength is arranged within the gain band of the active layer.
Journal ArticleDOI
Sub-picosecond all-optical gate utilizing aN intersubband transition.
TL;DR: By the improvement of the propagation property, sub-picosecond all-optical gate with an extinction ratio of more than 10 dB was accomplished with an input pulse energy of 150 pJ and the insertion loss with the switch on was improved.
