Journal ArticleDOI
Whispering gallery mode lasing in zinc oxide microwires
TL;DR: In this paper, a whispering gallery mode was demonstrated to be excited by optical pumping in single zinc oxide microwires fabricated by a simple carbothermal evaporation process with a lasing threshold of about 170kW∕cm2 at 10K.
Journal ArticleDOI
Raman tensor elements of β-Ga 2 O 3 .
TL;DR: The Raman spectra were measured in dependence on the polarization direction for backscattering on three crystallographic planes of β-Ga2O3 and modelled these dependencies using a modified Raman tensor formalism which takes birefringence into account.
Journal ArticleDOI
A practical, self-catalytic, atomic layer deposition of silicon dioxide.
Julien Bachmann,Julien Bachmann,Robert Zierold,Yuen Tung Chong,Roland Hauert,Chris Sturm,Rüdiger Schmidt-Grund,Bernd Rheinländer,Marius Grundmann,Ulrich Gösele,Kornelius Nielsch +10 more
TL;DR: This work describes a practical ALD process for SiO2 that overcomes limitations and describes a three-step reaction sequence based on 3-aminopropyltriethoxysilane, water, and ozone (O3) that can be envisioned for the ALD ofSiO2.
Journal ArticleDOI
Realization of a double-barrier resonant tunneling diode for cavity polaritons.
Hai Son Nguyen,D. V. Vishnevsky,Chris Sturm,Dimitrii Tanese,Dmitry Solnyshkov,Elisabeth Galopin,Aristide Lemaître,Isabelle Sagnes,Alberto Amo,Guillaume Malpuech,Jacqueline Bloch +10 more
TL;DR: It is shown that a nonresonant beam can be used as an optical gate and can control the device transmission, and distortion of the transmission profile when going to the high-density regime, signature of polariton-polariton interactions.
Journal ArticleDOI
All-optical phase modulation in a cavity-polariton Mach–Zehnder interferometer
Chris Sturm,Dimitrii Tanese,Hai Son Nguyen,Hugo Flayac,Elisabeth Galopin,Aristide Lemaître,Isabelle Sagnes,Dmitry Solnyshkov,Alberto Amo,Guillaume Malpuech,Jacqueline Bloch +10 more
TL;DR: An all-optical approach for controlling the phase of a flow of cavity-polaritons, making use of their strong interactions with localized excitons is proposed, by implementing a compact exciton–polariton interferometer, which output intensity and polarization can be optically controlled.
