Lecture Title(s)

Challenging the Limits of Difraction

This talk will show how to overcome three limits of optical diffraction. First, it will be shown how to focus light below the Abbe diffraction limit. Next it will be shown how to squeeze light through subwavelength holes in a metal screen, allowing for 100% transmission, in stark contrast to Bethe's aperture theory. Finally, it will be shown how to optically trap dielectric nanoparticles (~10 nm) with powers orders of magnitude smaller than required by conventional by Rayleigh scattering trapping formulations, which has interesting applications for manipulating viruses and quantum dots. Recent results on trapping and unfolding of single proteins will be presented.

Nanoplasmonics: Reaching out to the Single Molecule


Nanoplasmonics refers to the nanostructuring of metals to achieve enhanced light-matter interaction, down to the single molecule level. This talk will highlight some of our research advances towards single-molecule (and other) technologies. In particular, I will discuss reliable single molecule Raman by using the antenna concept of directivity. I will show how we can grab hold of single proteins with light, unfold them and also detect single protein binding with great sensitivity. Nanohole array surface plasmon resonance with 10^-7 refractive index unit resolution will be discussed. I will show how nanoplasmonics can improve THz sources, and can allow for enhanced second harmonic generation. Finally, I will talk about large field enhancements that can be achieved by combining nanoplasmonics with permittivity-near-zero materials.
