IEEE NY JOINT MTT AP PHO & NANO CHAPTER – SEMINAR: Controlling light down to the single-photon level with integrated quantum photonic devices

Abstract – Light-matter interactions allow adding functionalities to photonic on-chip devices, thus enabling developments in classical and quantum light sources, energy harvesters and sensors. These advances have been facilitated by precise control in growth and fabrication techniques that have opened new pathways to the design and realization of semiconductor devices where light emission, trapping and guidance can be efficiently controlled at the nanoscale.

In this context, I will show the implementation of semiconductor quantum dots in nano-photonic devices that can create simultaneously bright and pure, triggered single-photon sources [1], critical for quantum information technology. I will then present photonic geometries for controlling light propagation and brightness in broadband, scalable devices, based on plasmonic nanostructures [2].

Hybrid systems can allow overcoming limitations due to specific material properties and I will show how hybrid III-V/Silicon devices can be a platform for low-loss quantum light propagation [3]. I will also present a technique based on the transfer of semiconductor membranes embedding quantum emitters onto different host materials [4], for hybrid quantum photonic applications [5].

Finally, I will discuss novel photonic designs based on bio-inspired aperiodic [6] and disordered photonic crystals [7], showing efficient light confinement and optical sensing, and I will present our recent work on quantum biology, focused on the investigation of photosynthetic light harvesters on a chip.
