It is well known that elements from Group V of the periodic table behave similarly to hydrogen atoms when incorporated into a sing

Chin-Pang Liu

Dr Liu's research interests are focused on i) Design, fabrication and characterisation of advanced photonic devices, in particular, the Asymmetric Fabry-Perot modulator (AFPM) which can be used as both a light intensity modulator and a photodetector in a single device. ii) Radio-over-fibre systems and techniques. Novel and low-cost transmission techniques for wireless multiple-input-multiple-output (MIMO) signal over fibre. iii) Microwave Photonics. High-speed photonic sampling techniques.

  Nanopatterning techniques are crucial to realising the potential of nanoscience and nanotechnology in areas spanning from nanome

Martyn McLachlan

Dr McLachlan's research is the synthesis of three dimensionally periodic macroporous solids, specifically a class of materials referred to as synthetic opals. These materials posses a periodic arrangement of pores on a length scale which can be controllably altered from tens to hundreds of nanometres.

Stefan Maier

Professor Maier's research interests are in plasmonics and nanophotonics – finding ways to confine and guide light in a controlled manner on the nanoscale, below the optical diffraction limit. The main means to achieve this lies in the exploitation of surface plasmon polaritons (SPPs), electromagnetic surface waves supported at the interface between an electric conductor and a dielectric.

Joshua B. Edel

Professor Joshua Edel's research activities lie in the general area of nanobiotechnology with an emphasis on the development of micro and nanofluidic devices for analytical and bio-analytical applications and ultra-high sensitivity optical detection techniques. For example, tools are being developed to study molecular dynamics confined within 5 - 500 nm wide fluidic channels.

Neil Alford

Professor Neil Alford runs the Physical Electronics and Thin Film Materials group in the Department of Materials, Imperial College. The group have internationally recognised expertise in Pulsed Laser Deposition of ferroelectric based thin films and multilayer structures and their application for microwave tuneable devices.

Alwyn Seeds
