Asymmetric Chiral Coupling in a Topological Resonator
Shushu Shi, Xin Xie, Sai Yan +16
Chiral light-matter interactions supported by topological edge modes at the interface of valley photonic crystals provide a robust method to implement the unidirectional spin trans…
Controllable Spin-Resolved Photon Emission Enhanced by Slow-Light Mode in Photonic Crystal Waveguides on Chip
Shushu Shi, Shan Xiao, Jingnan Yang +17
We report the slow-light enhanced spin-resolved in-plane emission from a single quantum dot (QD) in a photonic crystal waveguide (PCW). The slow light dispersions in PCWs are desig…
Cavity Quantum Electrodynamics with Second-Order Topological Corner State
Xin Xie, Weixuan Zhang, Xiaowu He +11
Topological photonics provides a new paradigm in studying cavity quantum electrodynamics with robustness to disorder. In this work, we demonstrate the coupling between single quant…
Direct observation of nanofabrication influence on the optical properties of single self-assembled InAs/GaAs quantum dots
Jin Liu, Kumarasiri Konthasinghe, Marcelo Davanco +11
Single self-assembled InAs/GaAs quantum dots are a promising solid-state quantum technology, with which vacuum Rabi splitting, single-photon-level nonlinearities, and bright, pure,…
Zinc-blende and wurtzite GaAs quantum dots in nanowires studied using hydrostatic pressure
Shuang Yang, Kun Ding, Xiuming Dou +8
We report both zinc-blende (ZB) and wurtzite (WZ) crystal phase self-assembled GaAs quantum dots (QDs) embedding in a single GaAs/AlGaAs core-shell nanowires (NWs). Optical transit…
Tuning exciton and biexciton transition energies and fine structure splitting through hydrostatic pressure in single InGaAs quantum dots
Xuefei Wu, Hai Wei, Xiuming Dou +10
We demonstrate that the exciton and biexciton emission energies as well as exciton fine structure splitting (FSS) in single (In,Ga)As/GaAs quantum dots (QDs) can be efficiently tun…
Measurements of a fast nuclear spin dynamics in a single InAs quantum dot with positively charged exciton
X. M. Dou, B. Q. Sun, D. S. Jiang +2
By using highly time-resolved spectroscopy with an alternative σ+/σ - laser pulse modulation technique, we are able to measure the fast buildup and decay times of the dynamical nuc…
Temperature and Electron Density Dependence of Spin Relaxation in GaAs/AlGaAs Quantum Well
L. F. Han, Y. G. Zhu, X. H. Zhang +3
Temperature and carrier density dependent spin dynamics for GaAs/AlGaAs quantum wells (QWs) with different structural symmetry has been studied by using time-resolved Kerr rotation…
