Autor: Naoki Kumazaki, Tadataka Edamura, Kenichi Kasahara, Atsushi Sugiyama, Yohei Takagi, Naota Akikusa, Mikito Ishihara

Publikováno v: Japanese Journal of Applied Physics. 47:6320-6326

We report the experimental linewidth enhancement factor (α-factor) results on mid-infrared InGaAs/InAlAs quantum cascade lasers (QCLs) obtained using the self-mixing method. The waveforms appearing under self-mixing conditions were different from th

Integrated description of deformation modes in a sedimentary basin: A case study around a shallow drilling site in the Mizunami area, eastern part of southwest Japan

Autor: Kenji Amano, Naoki Kumazaki, Yasuto Itoh

Publikováno v: The Island Arc. 15:165-177

Tectonic episodes in a sedimentary basin are described on the basis of an integrated study combining reflection seismic interpretation, drilling survey and paleomagnetism. A shallow inclined borehole penetrated a fault shown by reflection seismic and

First Direct Observation of Small Linewidth Enhancement Factor of Fabry–Perot Quantum Cascade Laser

Autor: Naota Akikusa, Naoki Kumazaki, Tadataka Edamura, Mikito Ishihara, Yohei Takagi, Kenichi Kasahara

Publikováno v: Japanese Journal of Applied Physics. 47:1606-1608

We investigated the linewidth enhancement factor α of a Fabry–Perot quantum cascade laser by self-mixing interferometry. For the first time, the theoretically predicted characteristic waveform resulting from a small α of about -0.3 could be obtai
