Research projects:

My work concentrates on metamaterials and novel types of optical fibres, including sensing schemes using photonic crystal fibres (optical fibres with holes running along their length), composite metal/glass fibres, plasmonics, non-linear optics and acoustic/optic interaction in composite media.

Metamaterial fibres
with J Hayashi,, S. Atakaramians, R Lwin, H. Li, Shengling Wu, Alessio Stefani, S. Fleming, A. Argyros,

Metal/glass composite fibres are a new avenue for mass-producing metamaterials – materials with properties emerging from their structure rather than from their constituents. Such fibres behave as homogenous material, but with electromagnetic properties arising from sub-wavelength metal structures with electric and magnetic resonances, that can be tuned by design. In particular the effective refractive index of such fibres can be positive, negative or even one (making the fibre invisible in air), or highly anisotropic behaving as a metal in one direction and a dielectric in another. The latter configuration in particular enables sub-diffraction limited imaging.

In 2010, we published the first experimental demonstration of a  metamaterial fibre, which we demonstrated to have effective plasmonic response at terahertz frequencies; we also demonstrated numerically that similar fibres could be made that are indeed invisible at optical wavelengths. We demonstrated drawn fibres with magnetic resonances at THz frequencies. Our current work concentrates on the exploration  of new phenomena in structured fibre based metamaterials, their spatial dispersion and use for practical devices. As a first functional device, we have recently demonstrated deeply subwavelength imaging at THz freqeuncies using wire-array fibre and fibre taper, including focussing down to 1/27th of the wavelength and propagating sub-wavelength information over hundreds of wavelengths.

 

Imaging with hyperbolic media 
with Samiul Habib, Korbinian Kaltenecker, Daniel Collins, M. de Sterke, S. Atakaramians, A. Tuniz, S. Fleming, A. Argyros

Hyperbolic media are materials with effective electromagnetic properties radically different in different directions: typically they will behave as a metal in one direction and an insulator in another. As a consequence, light can propagate in these without diffraction, and evanescent wave can become propagative. This enables new kind of lenses beating the diffraction limit. We have recently demonstrated magnifying and non-magnifying hyperlenses (endoscopes) using metal/polymer wire array fibres, with resolution better than 1/30th of the wavelength at THz frequencies. We are studying such hyperlenses both experimentally and theoretically.

 

Metamaterial Waveguides
with Xiaoli Tang, Haisu Li, S. Atakaramians, A. Argyros, S. Fleming,

Metamaterials in principle enable an unprecedented control over electromagnetic waves, including confinement of light much below the diffraction limit. Metamaterials based sub-wavelength waveguides could provide a pathway to miniaturization of photonic circuits and THz optics and enhanced nonlinearities. Our programme concentrates on the theory of such waveguides as well as emerging devices based upon them.

 

 

 

 

Biography

Boris Kuhlmey is an Australian Research Council Future Fellow with the School of Physics, The University of Sydney, with a continuing appointment as Senior Lecturer.

After undergraduate studies at the École Normale Supérieure de Lyon, and a masters degree from the Institut d’Optique (Paris-Sud, Orsay, France) he was awarded a PhD jointly by the Université Aix Marseille III, France, and the School of Physics, University of Sydney, Australia, in 2003. During his PhD, he co-developed the multipole method for photonic crystal fibres (PCFs). In 2003 he joined the ARC Centre for Ultrahigh-bandwidth Devices for Optical Systems (CUDOS) at the University of Sydney, to work on modelling of photonic crystal fibres. In 2006 he was awarded an ARC fellowship for the theoretically study of solid core photonic bandgap fibres, followed by a continuing position as lecturer in 2009 and ARC Future Fellowship in 2010. He was Education and Training Director of CUDOS from 2007-2011 and became CI of CUDOS in 2011.

His achievements have recently been recognised through a NSW Young Tall Poppy Science award by the Australian Institute of Policy and Science. His research on drawn metamaterial has attracted funding from the US Air Force’s Asian Office of Aerospace Research and Development, as well as from the Australian Research Council, from which he has secured several competitive grants. In total, Dr Kuhlmey has been awarded over 1.7M$ in research grants over the last 5 years.


Boris is the author of the “
CUDOS MOF Utilities,” the first free software dedicated to the simulation of PCFs, and co-authored the book “Foundations of Photonic Crystal Fibres,” now in its second edition. He has authored and co-authored over 55 publications in refereed journals, has served as invited editor for Physica B and as secretary and public officer for the international ETOPIM society (Electrical, Transport and Optical Properties of Inhomogeneous Media). He has served on organization committees for several national and international conferences and workshops, including ETOPIM 7 (Sydney, 2006) and Photonic Crystals: Fundamentals to Devices (Sydney 2005), and was programme chair and cochair for several local workshops and tutorial workshops.
