EQEC Europe, and the US and European SPIE Conferences on Metamaterials. Professor Nikolay Zheludev is a world leader in the field of experimental nanophotonics and metamaterials.

The new research fields of nanophotonics and metamaterials are closely interlinked. The term Nanophotonics was coined only a few years ago and is now a major research direction in optical physics and engineering. Driven by the dream of untapped device functionality, nanophotonics studies the exciting science of the interaction of light with nanostructures, at the size scale where optical, electronic, structural, thermal and mechanical properties are deeply interdependent. Metamaterials are artificial electromagnetic media achieved by structuring on a sub-wavelength scale.

This field of research was catalyzed a few years ago by the intriguing opportunity to develop media that refract light in the opposite direction to that of normal media. Today nanophotonics and metamaterials are the most dynamic areas of physics, engineering and material science development which have been facilitated by the recent proliferation of nano-fabrication techniques such as high-resolution optical and electron beam lithography, focused ion milling and nanoimprint. Research centers and national programmes on nanophotonics and metamaterials are created all around the world as a core part of the nanotechnology revolution. Indeed, in the last twenty years photonics has played a key role in creating the world as we know it today, with enormous beneficial worldwide social impact.

The next photonic revolution will be explosively fuelled by a new dependence on active and switchable photonic metamaterials and nanophotonic devices.

Professor Zheludev started his academic career at the leading Russian research institute, the International Laser Centre at Moscow state University. His personal awards include the Wolfson Research Merit Award of the Royal Society and the Senior Leverhulme Research Award. With more than 500 referred publications and more than a hundred keynote, plenary and invited talks at major conferences in recent years, Professor Zheludev has made seminal contributions to various branches of optics, nonlinear optics, nanophotonics and metamaterials.

His early research was into the optics of intense laser fields, now widely known as nonlinear optics, the cornerstone science of today’s optical data storage and telecommunication technologies. His particular interests were in the fundamental aspects of the subject, such as nonlinear phenomena involving changes in the vectorial properties of light. Professor Zheludev’s interest in fundamental effects of light-matter interaction has led him to the fields of nanophotonics and metamaterials. Professor Zheludev started his career researching nonlinear polarization phenomena in optics.

This work was the first in a wide international research effort on controlling signals in nanophotonic plasmonic devices. He then demonstrated the fastest active plasmonic device ever that offers a terahertz bandwidth of operation and exploits the ultrafast nonlinearity of metal . Professor Zheludev was the first to show that a nanoscale source of plasmon signals can be created by the injection of free electrons into the metal surface and demonstrated the first nanoscale tunable light source on a chip driven by free electrons . In the field of metamaterials Professor Zheludev achieved a number of pioneering results.
