Event details
Join us on Monday 8th of May, at 1pm in the Physics Seminar Room (46/5081), for the QLM weekly seminar. We’re pleased to have Dr Luca Sapienza from the Solid-State Quantum Optics Group, who will be giving a talk titled “On-Chip Integrated Single-Photon Sources”.

Abstract
I will discuss the properties of semiconductor quantum dots as single-photon sources integrated on a chip.
In particular, I will present recent results in the implementation of metallic nano-rings for enhanced free-space extraction of light from solid-state emitters, achieving increases in the brightness of up to a factor 20, in a scalable, broadband geometry.
I will also show how atomic force microscopy combined with photoluminescence imaging gives insights into quantum dot growth and can be used to increase the yield of quantum photonic devices.
Finally, I will discuss a hybrid silicon/GaAs platform which allows quantum light sources to be integrated on silicon devices for integrated quantum and non-linear optics.

As always, tea, coffee and cake will be provided. We look forward to seeing you there!
