Plasmonic nanogap optical cavities: Confining light and heat in single molecules

Rohit Chikkaraddy

University of Cambridge, UK, United Kingdom

Light can be confined to extreme dimensions by strongly coupling surface plasmons between two metallic nanostructures spaced a few nanometres apart. In this talk, I will show how light confinement is achieved down to 1nm^3 approaching quantum limits enabling strong coupling, Purcell-enhanced emission and optomechanics with single-bond vibrations. I will further show how the heat inevitably generated in molecular bonds directly pumped by a mid-infrared laser provides unique opportunities for single-photon detectors and sensing the dynamic topology of cell membranes with sub-nm resolution.

Photothermal synthesis of single plasmonic core@shell nanoparticles

Andrea Baldi

Vrije Universiteit Amsterdam, Netherlands, The

Plasmon resonances in metal nanoparticles generate nanoscale temperature gradients that can activate chemical reactions. In typical ensemble experiments, however, these local gradients vanish due to collective heating [1]. Here, we demonstrate how plasmonic photothermal effects generate nanoreactors by activating and spectroscopically following the growth of individual metal@semiconductor core@shell nanoparticles [2]. Plasmonic synthesis of functional nanomaterials otherwise inaccessible with classical colloidal methods opens applications in nanolithography, catalysis, energy conversion, and photonic devices.

Large-area plasmonics in self-organised media

Francesco Buatier de Mongeot, Maria C Giordano

Università di Genova - Italy, Italy

Large-area nanoscale patterning of optical interfaces represents a key issue for developing real-world applications of plasmonic antenna arrays with tunable response from the visible to the IR range. Our recent results demonstrate that ion beam wrinkling is a viable tool for inducing self-organised restructuring on a broad portfolio of optical interfaces which range from dielectrics to flexible polymers. The approach is scalable to the industrial level as a single step maskless process for the fabrication of hybrid plasmonic/dielectric arrays capable of high sensitivity SEIRA sensing, colour-routing and multifunctional electro-optic applications.
