© 2019 American Physical Society. Spontaneous emission from excitonic transitions in InAs/GaAs quantum dots embedded in photonic crystal waveguides at 5 K into nonguided and guided modes is determined by direct spectral imaging. This enables measurem... Read More about 99% beta factor and directional coupling of quantum dots to fast light in photonic crystal waveguides determined by spectral imaging.
