Photonic-Crystal Waveguides with Disorder: Measurement of a Band-Edge Tail in the Density of States
S. R. Huisman, G. Ctistis, S. Stobbe +6
We measure localized and extended mode profiles at the band edge of slow-light photonic-crystal waveguides using phase-sensitive near-field microscopy. High-resolution band structu…
Experimental realization of highly-efficient broadband coupling of single quantum dots to a photonic crystal waveguide
T. Lund-Hansen, S. Stobbe, B. Julsgaard +5
We present time-resolved spontaneous emission measurements of single quantum dots embedded in photonic crystal waveguides. Quantum dots that couple to the photonic crystal waveguid…
Optical refrigeration with coupled quantum wells
R. S. Daveau, P. Tighineanu, P. Lodahl +1
Refrigeration of a solid-state system with light has potential applications for cooling small-scale electronics and photonics. We show theoretically that two coupled semiconductor…
Measuring the effective phonon density of states of a quantum dot
K. H. Madsen, P. Kaer, A. Kreiner-Møller +4
We employ detuning-dependent decay-rate measurements of a quantum dot in a photonic-crystal cavity to study the influence of phonon dephasing in a solid-state quantum-electrodynami…
Influence of multi-electronic states on few-quantum-dot nanolasers
J. Liu, S. Ates, M. Lorke +3
We present an experimental and theoretical study on the gain mechanism in a photonic-crystal-cavity nanolaser with embedded quantum dots. From time-resolved measurements at low exc…
Mutual Coupling of two Semiconductor Quantum Dots via an Optical Nanocavity Mode
A. Laucht, J. M. Villas-Bôas, S. Stobbe +7
We present an experimental and theoretical study of a system consisting of two spatially separated self-assembled InGaAs quantum dots strongly coupled to a single optical nanocavit…
