Quantum NanoPhotonics and Metamaterials
Promoting an extreme control of light and matter interaction quantum nano-photonics empowers novel femto- and attosecond and nano-photonic phenomena, forming the basis for quantum photonics and innovative nano-photonic lasers.
And the "metamaterial" concept to control photons and electrons by the principle "function from structure" has inspired scientists to conceive perfect lenses, new lasers, 'invisibility' and acoustic cloaks and opened the door to slow and stopped broadband light with applications in quantum science and technology, sensing and nano-chemistry.
The Quantum Nano-Photonics group studies the physics of nanophotonics and optical and electronic metamaterials and advanced lasers, and investigates the (ultrafast) nonlinear and quantum dynamics of nano-plasmonic and nano-photonic materials and (complex) nano-photonic systems with gain. Concurrently, the group is striving to embed metamaterials in new realms of applications in information and laser technology, nanophotovoltaics and the bio-medical sciences.

Professor Ortwin Hess holds the Chair Professorship in Quantum Nanophotonics at Trinity College Dublin and the Leverhulme Chair in Metamaterials in the Blackett Laboratory/Department of Physics of Imperial College London.
Professor Hess studied physics at the University of Erlangen and the Technical University of Berlin. Following pre- and post-doctoral times in Edinburgh and at the University of Marburg, Hess has been (from 1995 to 2003) Head of the Theoretical Quantum Electronics Group at the Institute of Technical Physics in Stuttgart, Germany. He has a Habilitation in Theoretical Physics at the University of Stuttgart (1997) and became Adjunct Professor in 1998. Since 2001 he is Docent of Photonics at Tampere University of Technology in Finland. Professor Hess has been Visiting Professor at Stanford University (1997 - 1998) and the University of Munich (2000 - 2001). From 2003 to 2010 he was Professor of Theoretical Condensed Matter and Optical Physics in the Department of Physics and the Advanced Technology Institute at the University of Surrey in Guildford, UK.
Professor Hess's research interests and activities are in condensed matter quantum optics and are currently focused on quantum photonics, optical and electronic metamaterials, spatio-temporal laser dynamics and computational photonics.
Bridging theoretical condensed-matter physics, quantum optics and laser physics, Professor Hess has pioneered the research fields and concepts of active nano-plasmonics and optical metamaterials with quantum gain and made seminal contributions to spatio-temporal dynamics of semiconductor lasers.
Hess has discovered the ‘trapped-rainbow’ principle and recently introduced and explained the idea of cavity-free ‘stopped-light lasing’.
He has further contributed significantly to quantum dot photonics [book (Imperial College Press, 2012)] and computational modeling of photonic crystals as well as to the quantum theory of temperature on the nano-scale [several book chapters].
Hess combines theoretical solid state (quantum) optics with computational photonics, involving the development of innovative approaches and techniques leading to the realization of a unique and flexible family of codes for active nano-plasmonics and (inherently multi-scale) metamaterials as well as nonlinearities and the microscopic spatio-temporal interplay of intense light with nano-structured materials (semiconductors, polymers, etc) on ultrafast time-sclaes.
He strives to explore the dynamics and light-matter interaction in active (nonlinear, gain-enhanced and dynamic) nanophotonic metamaterials, the physics of self-organised (polymer based) nanoplasmonic chiral metamaterials, semiconductor quantum nanomaterials, quantum dots and graphene with gain as well as the dynamics and quantum fluctuations of slow and stopped light and ultrafast (nano-) lasers. Further plans are the study of the ultrafast spatio-temporal dynamics in nano-plasmonics and the control of spontaneous and amplified spontaneous emission.
