Journal ArticleDOI
An electrically pumped polariton laser
Sven Höfling,M. Amthor,Arash Rahimi-Iman,Na Young Kim,Julian Fischer,Ivan Savenko,Vladimir D. Kulakovski,Ivan A. Shelykh,Stephan Reitzenstein,Alfred Forchel,Yoshihisa Yamamoto,Martin Kamp,Christian Schneider +12 more
TL;DR: An electrically pumped polariton laser based on a microcavity containing multiple quantum wells is presented, which can be extended to room-temperature operation using wide-bandgap materials and proves polariton Laser emission unambiguously.
Journal ArticleDOI
Characterization of an abnormal photoluminescence behavior upon crystal-phase transition of perovskite CH3NH3PbI3
TL;DR: Both PL and XRD results unambiguously prove the coexistence of the tetragonal and orthorhombic phases of MAPbI3 in the temperature range of 150 to 130 K.
Journal ArticleDOI
Influence of the substrate material on the optical properties of tungsten diselenide monolayers
Sina Lippert,Lorenz Maximilian Schneider,Dylan Renaud,Kyungnam Kang,Obafunso Ajayi,Jan Kuhnert,Marc-Uwe Halbich,Oday Mazin Abdulmunem,Xing Lin,Khaleel I. Hassoon,Saeideh Edalati-Boostan,Young Duck Kim,Wolfram Heimbrodt,Eui-Hyeok Yang,James Hone,Arash Rahimi-Iman +15 more
TL;DR: In this article, a comparison of optical properties of tungsten-diselenide monolayers on different substrates is presented, and small differences in emission energy and decay dynamics have been observed depending on the substrate.
Journal ArticleDOI
From polariton condensates to highly photonic quantum degenerate states of bosonic matter
Marc Assmann,Jean-Sebastian Tempel,Franziska Veit,Manfred Bayer,Arash Rahimi-Iman,Andreas Löffler,Sven Höfling,Stephan Reitzenstein,Lukas Worschech,Alfred Forchel +9 more
TL;DR: It is shown that key signatures of BEC can even be observed without fulfilling the self-equilibrium condition in a highly photonic quantum degenerate nonequilibrium system.
Journal ArticleDOI
Mode-locked semiconductor disk lasers
Mahmoud A. Gaafar,Arash Rahimi-Iman,Ksenia A. Fedorova,Wolfgang Stolz,Edik U. Rafailov,Martin Koch +5 more
TL;DR: In this paper, a review of the recent advances in the field of ultrashort pulse generation from optically pumped vertical-external-cavity surface-emitting lasers (OP-VECSELs) is presented.
