TuC1.1 - OPTICAL BIOSENSING WITH SILICON-NITRIDE MICRORESONATORS

Abstract

Abstract

Silicon-nitride (SiN) microresonators have become versatile tools of linear, nonlinear, and quantum optics. In this talk, we will describe the design of SiN microresonators with adjustable dispersion and Q-factors, and will also discuss the experiments on sensing biological neurotransmitters using SiN microrings.

WE1.2 - Ultrafast nonlinear optical properties and polarisation control with complex plasmonic nanostructures

Abstract

Abstract

We show that via engineering inhomogeneous electron temperature distribution in hybrid plasmonic nanoparticles and self-assembled metamaterials, accelerated or delayed nonlinear optical response can be designed with the enhanced Kerr-type nonlinearity. Combined with anisotropic properties of metamaterials, nonlinearity leads to efficient all-optical control of light polarisation.
