Abstract:
We resonantly excite a semiconductor quantum dot micropillar device with a low background cavity reflectivity of just 0.0089, which allows a signal to background ratio of 50 and an overall system responsivity of 3 %. At few-photon excitation levels, we observe the Mollow triplets without resort to any laser background rejection technique.
