Research Themes Overview

Optofluidics

Optofluidic hollow-core photonic crystal fibre (HC-PCF) allows light to be guided at the centre of a microfluidic channel, maximizing its interaction with liquids and particles. This system offers unique opportunities to study photochemical reactions and in advanced optical trapping experiments.

microcavitiesMicrocavities

Microcavities are wavelength-sized optical cavities that trap light of a specific colour with a wavelength set by the cavity length. If an emitting layer (such as a semiconductor) is embedded in this cavity, tuned to emit/absorb at the same wavelength ...

polymeropalsPolymer Opals

These are structural colour materials, made cheaply from nano-assembly on the metre- to kilometre-scales. The colour comes from the scattering of light inside the regularly arranged nanostructure, and we invented a way to order vast arrays of spheres using shear forces ...

Cavity Plasmonics

The field of plasmonics aims to exploit the unique optical properties of nanometallic structures to control and manipulate light. We have now been able to confine light to the nanometre scale, allowing us to watch single molecules and even atom movements in real time...

Active Plasmonics

One of the enormous advantages of plasmonic nanoparticles lies in the fact that simply changing the geometry of the nanostructure, for example from a spherical particle to a rod shape, allows unprecedented control over the location and magnitude of the concentrated electric fields ...

Plasmonic Chemistry/ SensingPlasmonic Chemistry/Sensing

The extreme confinement of light into tiny gaps allows us to watch chemistry in real time at the single molecule level, and to detect trace concentrations of molecules. It also enables us to see your neurotransmitters from your urine, and explore how individual molecules in cell membranes move around...
