Optical Spin Initialization and Non-Destructive Measurement in a Quantum Dot Molecule
Danny Kim, Sophia E. Economou, Stefan C. Badescu +5
The spin of an electron in a self-assembled InAs/GaAs quantum dot molecule is optically prepared and measured through the trion triplet states. A longitudinal magnetic field is use…
Fine structure and optical pumping of spins in individual semiconductor quantum dots
Allan S. Bracker, Daniel Gammon, Vladimir L. Korenev
We review spin properties of semiconductor quantum dots and their effect on optical spectra. Photoluminescence and other types of spectroscopy are used to probe neutral and charged…
Coherent Population Trapping of an Electron Spin in a Single Negatively Charged Quantum Dot
Xiaodong Xu, Bo Sun, Paul R. Berman +4
Coherent population trapping (CPT) refers to the steady-state trapping of population in a coherent superposition of two ground states which are coupled by coherent optical fields t…
Antibonding ground states in semiconductor artificial molecules
M. F. Doty, J. I. Climente, M. Korkusinski +4
The spin-orbit interaction is a crucial element of many semiconductor spintronic technologies. Here we report the first experimental observation, by magneto-optical spectroscopy, o…
A Single Charged Quantum Dot in a Strong Optical Field: Absorption, Gain, and the AC Stark Effect
Xiaodong Xu, Bo Sun, Erik D. Kim +6
We investigate a singly-charged quantum dot under a strong optical driving field by probing the system with a weak optical field. When the driving field is detuned from the trion t…
