Giant optomechanical coupling and dephasing protection with cavity exciton-polaritons
P. Sesin, A. S. Kuznetsov, G. Rozas +6
Electronic resonances can significantly enhance the photon-phonon coupling in cavity optomechanics, but are normally avoided due to absorption losses and dephasing by inhomogeneous…
Photoluminescence of double quantum wells: asymmetry and excitation laser wavelength effects
C. A. Bravo-Velazquez, L. F Lastras-Martinez, O. Ruiz-Cigarrillo +4
Circularly polarized photoluminescence (PL) spectroscopy measured at 19 K on GaAs/AlGaAs symmetric and asymmetric double quantum wells (DQW) is reported. The PL is obtained by exci…
Optomechanical parametric oscillation of a quantum light-fluid lattice
A. A. Reynoso, G. Usaj, D. L. Chafatinos +6
Two-photon coherent states are one of the main building pillars of non-linear and quantum optics. It is the basis for the generation of minimum-uncertainty quantum states and entan…
Flying electron spin control gates
Paul L. J. Helgers, James A. H. Stotz, Haruki Sanada +3
The control of "flying" (or moving) spin qubits is an important functionality for the manipulation and exchange of quantum information between remote locations on a chip. Typically…
Remotely pumped GHz antibunched emission from single exciton centers in GaAs
M. Yuan, K. Biermann, S. Takada +2
Quantum communication networks require on-chip transfer and manipulation of single particles as well as their interconversion to single photons for long-range information exchange.…
Electrical suppression of spin relaxation in GaAs(111)B Quantum Wells
A. Hernández-Mínguez, K. Biermann, R. Hey +1
Spin dephasing via the spin-orbit interaction (SOI) is a major mechanism limiting the electron spin lifetime in III-V zincblende quantum wells. The dephasing can be suppressed in G…
Electric control of spin transport in GaAs (111) quantum wells
A. Hernández-Mínguez, K. Biermann, R. Hey +1
We show by spatially and time-resolved photoluminescence that the application of an electric field transverse to the plane of an intrinsic GaAs (111) quantum well (QW) allows the t…
Sidewall quantum wires on GaAs(001) substrates
Paul L. J. Helgers, Haruki Sanada, Yoji Kunihashi +2
We study the structural, optical, and transport properties of sidewall quantum wires on GaAs(001) substrates. The QWRs are grown by molecular beam epitaxy (MBE) on GaAs(001) substr…
Tunneling blockade and single-photon emission in GaAs double quantum wells
M. Yuan, A. Hernández-Mínguez, K. Biermann +1
We report on the selective excitation of single impurity-bound exciton states in a GaAs double quantum well (DQW). The structure consists of two quantum wells (QWs) coupled by a th…
Asymmetric tensor in low-symmetry two-dimensional hole systems
C. Gradl, R. Winkler, M. Kempf +8
The complex structure of the valence band in many semiconductors leads to multifaceted and unusual properties for spin-3/2 hole systems compared to typical spin-1/2 electron system…
