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…
Evolution of excitons via biexcitons to an electron-hole plasma without level crossing between band edge and exciton in a quantum wire
Masahiro Yoshita, Yuhei Hayamizu, Hidefumi Akiyama +4
A recent single quantum wire is of sufficient quality to reveal new details of the photoluminescence (PL) evolution with increasing electron--hole (e--h) pair density. At a pair de…
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…
Polarization-dependent photoluminescence-excitation spectra of one-dimensional exciton and continuum states in T-shaped quantum wires
Hirotake Itoh, Yuhei Hayamizu, Masahiro Yoshita +5
We measured polarization-dependent photoluminescence-excitation spectra of highly uniform T-shaped quantum wires at 5 K. We attribute one peak to the 1D-exciton ground state and th…
