Sub-Cycle Optical Response Caused by Dressed State with Phase-Locked Wavefunctions
K. Uchida, T. Otobe, T. Mochizuki +7
The coherent interaction of light with matter imprints the phase information of the light field on the wavefunction of the photon-dressed electronic state. Driving electric field,…
Time-resolved observation of coherent excitonic nonlinear response with a table-top narrowband THz pulse wave
K. Uchida, H. Hirori, T. Aoki +9
By combining a tilted-pulse-intensity-front scheme using a LiNbO3 crystal and a chirped-pulse-beating method, we generated a narrowband intense terahertz (THz) pulse, which had a m…
Metal-to-insulator transition in anatase TiO2 thin films induced by growth rate modulation
T. Tachikawa, M. Minohara, Y. Nakanishi +5
We demonstrate control of the carrier density of single phase anatase TiO2 thin films by nearly two orders of magnitude by modulating the growth kinetics during pulsed laser deposi…
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…
Intersubband electronic Raman scattering in narrow GaAs single quantum wells dominated by single-particle excitations
Takeya Unuma, Kensuke Kobayashi, Aishi Yamamoto +6
We measured resonant Raman scattering by intersubband electronic excitations in GaAs/AlAs single quantum wells (QWs) with well widths ranging from 8.5 to 18 nm. In narrow (less tha…
