Turning off quantum duality
X. -F. Qian, K. Konthasinghe, K. Manikandan +3
We provide the first experimental confirmation of a three-way quantum coherence identity possessed by single pure-state photons. Our experimental results demonstrate that tradition…
Buried heterostructure vertical-cavity surface-emitting laser with semiconductor mirrors
G. Zhao, Y. Zhang, D. G. Deppe +2
We report a buried heterostructure vertical-cavity surface-emitting laser fabricated by epitaxial regrowth over an InGaAs quantum well gain medium. The regrowth technique enables m…
Wave-Particle Duality Controlled by Single-Photon Self-Entanglement
X. -F. Qian, K. Konthasinghe, S. K. Manikandan +3
We experimentally observe that quantum duality of a single photon is controlled by its self-entanglement through a three-way quantum coherence identity . Here V, D,…
Coherent versus Incoherent Light Scattering from a Quantum Dot
K. Konthasinghe, J. Walker, M. Peiris +8
We analyze the light scattered by a single InAs quantum dot interacting with a resonant continuous-wave laser. High resolution spectra reveal clear distinctions between coherent an…
Two-Color Photon Correlations of the Light Scattered by a Quantum Dot
M. Peiris, B. Petrak, K. Konthasinghe +3
Two-color second-order correlations of the light scattered near-resonantly by a quantum dot were measured by means of spectrally-filtered coincidence detection. The effects of filt…
