Optical control of excited-state lifetimes

David Andrews and David S. Bradshaw - Electronic excitation of particles in fluorescent materials can now be controlled using laser-assisted energy-transfer techniques. Read full article HERE.

The optical assembly of nanoparticles

David Andrews and Luciana Dávila Romero - Laser light can induce binding or repulsive forces between particles and thus facilitate manipulation of nanoparticle arrays. Read full article HERE.

Our research broadly concerns the development of fundamental theory to elicit quantum, photonic and nanoscale features in light-matter interactions.  Present research topics fall into four main areas:

• Molecular energy transfer and light harvesting, focusing on both linear and nonlinear mechanisms in dendrimers and other multi-chromophore systems;
• Nonlinear optics and photonics, including multiphoton and optically-switched molecular fluorescence and related interactions;
• The properties and coupling interactions of structured light and optical vortices, especially with regard to optical angular momentum and surface plasmon interactions;
• Laser-induced optical binding and related, inter-particle nanoscale forces. 

All this research is constructed on the basis of a consistent quantum electrodynamical representation that affords rigour in the formulation of photonic processes, and which facilitates the identification of new mechanisms and mechanistic connections.
