Abstract

AbstractWe developed a high‐resolution Michelson interferometer in order to stabilize the relative phase of double pulses by using a He‐Ne two‐frequency laser positioning system. A very stable phase‐locked pulse pair whose phase difference was only 4° at 900 nm was realized. Using a high‐resolution Michelson interferometer, we demonstrated coherent control of an exciton in a GaAs/AlGaAs crescent‐shaped quantum wire. The dephasing time of the single quantum wire was 400 fs. © 2011 Wiley Periodicals, Inc. Electron Comm Jpn, 94(5): 25–32, 2011; Published online in Wiley Online Library (wileyonlinelibrary.com).
