Room-temperature excitonic absorption in quantum wires
Yasushi Takahashi, Yuhei Hayamizu, Hirotake Itoh +4
We measured absorption spectra of T-shaped quantum wires at room temperature using waveguide-transmission spectroscopy. Strong and narrow room-temperature one-dimensional-exciton a…
Strong photo-absorption by a single quantum wire in waveguide-transmission spectroscopy
Yasushi Takahashi, Yuhei Hayamizu, Hirotake Itoh +4
We measured the absorption spectrum of a single T-shaped, 14x6 nm lateral-sized quantum wire embedded in an optical waveguide using waveguide-transmission spectroscopy at 5 K. In s…
Imaging of emission patterns in a T-shaped quantum wire laser
Yasushi Takahashi, Shinichi Watanabe, Masahiro Yoshita +5
Spatially and spectrally resolved microscopic images of spontaneous and stimulated emissions are imaged at the mirror facets of a GaAs T-shaped quantum wire laser with high uniform…
