Scarpelli, L., Lang, B., Masia, F., Beggs, D., Muljarov, E., Young, A., …Langbein, W. (2019). 99% beta factor and directional coupling of quantum dots to fast light in photonic crystal waveguides determined by spectral imaging. Physical Review B, 100(3), https://doi.org/10.1103/PhysRevB.100.035311

Spontaneous emission from excitonic transitions in InAs/GaAs quantum dots embedded in pho-tonic crystal waveguides at 5 K into non-guided and guided modes is determined by direct spectral imaging. This enables measurement of the absolute coupling eff...
