Periodic Reporting for period 4 - LIVIN (Light-Vapour Interactions at the Nanoscale)

Berichtszeitraum: 2019-12-01 bis 2020-05-31

Zusammenfassung vom Kontext und den Gesamtzielen des Projekts

The goal of this project is to study and better understand the interaction of light with atomic vapors at the nanoscale, as well as to demonstrate the usefulness of such interactions for chip scale practical applications.
It addresses the question of miniaturization versus performance. Is there a penalty in performance due to miniaturization? and if so, what is it and how it can be corrected? Finally, can we use the concept and technology to demonstrate devices for "real life" applications?
The importance and significance of the project for the society comes both from the aspect of fundamental understanding as well as from the great potential of achieving promising applications. In fact, the developed technology can lead to promising applications such as chip scale optical buffers and optical switching, frequency references and atomic clocks, and chip scale magnetometry.

Arbeit, die ab Beginn des Projekts bis zum Ende des durch den Bericht erfassten Berichtszeitraums geleistet wurde, und die wichtigsten bis dahin erzielten Ergebnisse

The project started by demonstrating our ability to achieve chip scale atomic spectroscopy. Next, we reported chip scale spectroscopy in long waveguides, with the capability of operating at more relaxed temperatures (around 65 Degrees centigrade) due to the longer interaction of light with vapors. Furthermore, we observe fascinating effects such as light shift and strong coupling. Furthermore, we demonstrated for the first time vapor-cavity interactions on a chip. We tuned the photonic resonance to the atomic resonance and controlled the dispersion. The enhancement of optical power in the cavity turned out to be crucial in reducing the amount of optical power needed to perform all optical switching.

Fortschritte, die über den aktuellen Stand der Technik hinausgehen und voraussichtliche potenzielle Auswirkungen (einschließlich der bis dato erzielten sozioökonomischen Auswirkungen und weiter gefassten gesellschaftlichen Auswirkungen des Projekts)

The obtained results goes beyond the state of the art. For example, we have shown the interactions of plasmonic and atomic resonance in the presence of magnetic field, which was not demonstrated before. This might lead to new ways of performing magnetic imaging, and perhaps to advances versions of low cost MRI technology. This obviously will have a tremendous socio-economic impact.
