Filter‐free single photon emission in an integrated cavity‐waveguide device
10:30 - 10:50
Glenn Solomon, Tobias Huber, Markus Müller, Yichen Shuai and Marcelo Davanco We have fabricated and tested an integrated chip-scale single-photon source based on the coupling of micro-pillar cavities containing QDs connected to ridge waveguides. This geometry allows us to resonantly excite single QDs in several cavities in the chip plane via a single waveguide, while the quantum light is directed vertically off-chip. Our measurements are completely filter-free: QD light is directly collected from the sample and (broadband) fiber-coupled into our detection scheme. Furthermore, while cross-polarization, with its 50% loss, is required in most resonant excited QD cavity structures, it is eliminated here. Autocorrelation measurements demonstrates zero (within error) multi-photon light contribution.
