Dynamics of resonantly excited excitons in MoSe $_{2}$ and WS $_{2}$ single-layers monitored with four-wave mixing

Tomasz Jakubczyk, Miroslav Bartos, Karol Nogajewski +4

We investigate dynamics of resonantly excited excitons in single-layers of MoSe $_{2}$ and WS $_{2}$ down to 4.5 K. To this end, we measure the delay dependence of the heterodyne four-wa…

99% beta factor and directional coupling of quantum dots to fast light in photonic crystal waveguides determined by hyperspectral imaging

L. Scarpelli, B. Lang, F. Masia +8

Spontaneous emission from excitonic transitions in InAs/GaAs quantum dots embedded in photonic crystal waveguides at 5K into non-guided and guided modes is determined by direct hyp…

Coherence and density dynamics of excitons in a single-layer MoS $_{2}$ reaching the homogeneous limit

Tomasz Jakubczyk, Goutham Nayak, Lorenzo Scarpelli +13

We measure the coherent nonlinear response of excitons in a single-layer of molybdenum disulphide embedded in hexagonal boron nitride, forming a $h$ -BN/MoS $_{2}$ / $h$ -BN heterostructu…
