Journal ArticleDOI
Room-temperature polariton lasing in semiconductor microcavities.
Stavros Christopoulos,G. Baldassarri Höger von Högersthal,A. J. D. Grundy,Pavlos G. Lagoudakis,Alexey Kavokin,Jeremy J. Baumberg,Gabriel Christmann,Raphaël Butté,Eric Feltin,J.-F. Carlin,Nicolas Grandjean +10 more
TL;DR: Angular and spectrally resolved luminescence show that the polariton emission is beamed in the normal direction with an angular width of +/-5 degrees and spatial size around 5 microm.
Journal ArticleDOI
Current status of AlInN layers lattice-matched to GaN for photonics and electronics
Raphaël Butté,J.-F. Carlin,Eric Feltin,M. Gonschorek,Sylvain Nicolay,Gabriel Christmann,D. Simeonov,A. Castiglia,J. Dorsaz,H. J. Buehlmann,Stavros Christopoulos,G. Baldassarri Höger von Högersthal,A. J. D. Grundy,Mauro Mosca,Mauro Mosca,C. Pinquier,C. Pinquier,M. A. Py,F. Demangeot,J. Frandon,Pavlos G. Lagoudakis,Jeremy J. Baumberg,Nicolas Grandjean +22 more
TL;DR: In this paper, the structural and optical properties of lattice-matching AlInN layers to GaN have been investigated and their specific use to realize nearly strain-free structures for photonic and electronic applications has been discussed.
Journal ArticleDOI
Spontaneous Polarization Buildup in a Room-Temperature Polariton Laser
Jeremy J. Baumberg,Alexey Kavokin,Stavros Christopoulos,A. J. D. Grundy,Raphaël Butté,Gabriel Christmann,Dmitry Solnyshkov,Guillaume Malpuech,G. Baldassarri Höger von Högersthal,Eric Feltin,J.-F. Carlin,Nicolas Grandjean +11 more
TL;DR: The Stokes vector of emitted light changes its orientation randomly from one excitation pulse to another, so that the time-integrated polarization remains zero, which is completely different from any previous laser.
Journal ArticleDOI
Blue lasing at room temperature in an optically pumped lattice-matched AlInN=GaN VCSEL structure
Eric Feltin,Gabriel Christmann,J. Dorsaz,A. Castiglia,J.-F. Carlin,Raphaël Butté,Nicolas Grandjean,Stavros Christopoulos,G. Baldassarri Höger von Högersthal,A. J. D. Grundy,Pavlos G. Lagoudakis,Jeremy J. Baumberg +11 more
TL;DR: In this article, a crack-free planar vertical cavity surface emitting laser (VCSEL) structure based on a bottom lattice-matched AllnN/GaN distributed Bragg reflector (DBR) and a top dielectric DBR is presented.
Journal ArticleDOI
Optical analogue of the spin Hall effect in a photonic cavity
Maria Maragkou,Caryl E. Richards,Tomas Ostatnický,A. J. D. Grundy,Joanna M. Zajac,Maxime Hugues,Wolfgang Werner Langbein,Pavlos G. Lagoudakis +7 more
TL;DR: It is observed that anisotropy in the polarization flux generated in a GaAs/AlAs photonic cavity by optical illumination, equivalent to spin currents in strongly coupled microcavities, constitutes the optical analogue of the spin Hall effect.
