Journal ArticleDOI
Liquid-crystal lasers
Harry J. Coles,Stephen M. Morris +1 more
TL;DR: In this article, the scientific origins of the technology of liquid-crystal laser and reviews the current cutting-edge research are discussed. But the focus of this paper is on the current state of the art.
Journal ArticleDOI
Liquid crystal ‘blue phases’ with a wide temperature range
TL;DR: It is proposed that the unusual behaviour of these blue phase materials is due to their dimeric molecular structure and their very high flexoelectric coefficients, which sets out new theoretical challenges and potentially opens up new photonic applications.
Journal ArticleDOI
Optical Manifestations of Planar Chirality
A. Papakostas,A. Potts,Darren M. Bagnall,Sergey L. Prosvirnin,Harry J. Coles,Nikolay I. Zheludev +5 more
TL;DR: It is reported that planar chiral structures affect the polarization state of light in a manner similar to three-dimensional chiral (optical active) media.
Journal ArticleDOI
Blue-phase templated fabrication of three-dimensional nanostructures for photonic applications
Flynn Castles,Francesca Day,Stephen M. Morris,Doo-Hyun Ko,Damian J. Gardiner,Malik M. Qasim,S. Nosheen,Philip J.W. Hands,Su Seok Choi,Richard H. Friend,Harry J. Coles +10 more
TL;DR: The fabrication of self-assembled three-dimensional nanostructures by polymer templating blue phase I, a chiral liquid crystal with cubic symmetry, are demonstrated, which have unprecedented thermal stability and act as both mirrorless lasers and switchable electro-optic devices.
Journal ArticleDOI
The parameter space of graphene chemical vapor deposition on polycrystalline Cu
Piran R. Kidambi,Caterina Ducati,Bruno Dlubak,Damian J. Gardiner,Robert S. Weatherup,Marie-Blandine Martin,Marie-Blandine Martin,Pierre Seneor,Pierre Seneor,Harry J. Coles,Stephan Hofmann +10 more
TL;DR: In this paper, a systematic study of the parameter space of CVD on polycrystalline Cu foils is presented, aiming at a more fundamental process rationale in particular regarding the choice of carbon precursor and mitigation of Cu sublimation.
