Open access optical microcavities for controlled light-matter interactions

Date 16 April 2018 Time 11:00 - 12:00
Location AMOLF Lecture Room
Speaker Jason Smith (University of Oxford, Oxford)
Category Public Colloquium

Optical microcavities are an important tool in the photonics toolbox, providing for enhancement and control of light-matter interactions to unveil new physics and realise novel device applications. In the past 10 years, advances in fabrication techniques have led to the realisation of miniature Fabry Pérot cavities, or ‘open microcavities’, that provide a flexible tool for light-matter coupling, offering facile control over coupling and spectral tuning not available with other microcavity designs. In this talk I will present some of the work we have been carrying out at Oxford on the fabrication of such cavities and their application to diverse topics such as quantum technologies with nitrogen-vacancy colour centres in diamond, polariton systems in 2D materials, and the sensing and analysis of nanoparticles in fluids. I will also describe our recent efforts to bring these devices ‘out of the laboratory’ to commercial availability.
