Journal ArticleDOI
MBE-grown metamorphic lasers for applications at telecom wavelengths
N. N. Ledentsov,Vitaly Shchukin,T. Kettler,K. Posilovic,Dieter Bimberg,L. Ya. Karachinsky,A.Yu. Gladyshev,Mikhail V. Maximov,Innokenty I. Novikov,Yu. M. Shernyakov,A. E. Zhukov,V. M. Ustinov,A. R. Kovsh +12 more
TL;DR: In this article, the authors studied growth phenomena and structural and optical properties of metamorphic (MM) quantum dots (QDs) and QD lasers emitting in the 1.4-1.5-μm range.
Journal ArticleDOI
1.9 W continuous-wave single transverse mode emission from 1060 nm edge-emitting lasers with vertically extended lasing area
M. J. Miah,T. Kettler,K. Posilovic,Vladimir Kalosha,D. Skoczowsky,Ricardo Rosales,Dieter Bimberg,J. Pohl,Markus Weyers +8 more
TL;DR: In this article, a ridge waveguide (RW) with 9'μm stripe width and 2.64'mm cavity length was used to achieve 1.9 W single transverse mode optical power under continuous-wave (cw) operation.
Journal ArticleDOI
Metamorphic 1.5 µm-range quantum dot lasers on a GaAs substrate
L. Ya. Karachinsky,T. Kettler,Innokenty I. Novikov,Yu. M. Shernyakov,N. Yu. Gordeev,Mikhail V. Maximov,N. V. Kryzhanovskaya,Alexey E. Zhukov,Elizaveta Semenova,A. P. Vasil’ev,V. M. Ustinov,Gerrit Fiol,Matthias Kuntz,A. Lochmann,O. Schulz,L. Reissmann,K. Posilovic,A. R. Kovsh,S. S. Mikhrin,Vitaly Shchukin,Nikolay N. Ledentsov,Dieter Bimberg +21 more
TL;DR: In this paper, a defect reduction technique (DRT) was used on InAs/InGaAs quantum dots (QDs) grown on metamorphic (In, Ga, Al)As layers, which were previously deposited on GaAs substrates using defect reduction techniques.
Journal ArticleDOI
High-Power Low-Beam Divergence Edge-Emitting Semiconductor Lasers with 1- and 2-D Photonic Bandgap Crystal Waveguide
Mikhail V. Maximov,Y.M. Shernyakov,Innokenty I. Novikov,L. Ya. Karachinsky,N. Yu. Gordeev,U. Ben-Ami,D. Bortman-Arbiv,A. Sharon,Vitaly Shchukin,Nikolay N. Ledentsov,T. Kettler,K. Posilovic,Dieter Bimberg +12 more
TL;DR: In this article, edge-emitting lasers based on the 1-and 2-dimensional longitudinal photonic bandgap crystal (PBC) concept are proposed. But the authors focus on the edge-EME design, which allows a robust and controllable extension of the fundamental mode.
Journal ArticleDOI
Degradation-robust single mode continuous wave operation of 1.46μm metamorphic quantum dot lasers on GaAs substrate
T. Kettler,L. Ya. Karachinsky,N. N. Ledentsov,V. A. Shchukin,Gerrit Fiol,Matthias Kuntz,A. Lochmann,O. Schulz,L. Reissmann,K. Posilovic,Dieter Bimberg,I. I. Novikov,Yu. M. Shernyakov,N. Yu. Gordeev,Mikhail V. Maximov,N. V. Kryzhanovskaya,A. E. Zhukov,Elizaveta Semenova,A. P. Vasil’ev,V. M. Ustinov,A. R. Kovsh +20 more
TL;DR: In this article, a single-mode 800mW output power in the pulsed regime is obtained for a 6μm ridge width for InAs∕InGaAs quantum dots grown on metamorphic (In,Ga,Al)As layers deposited on GaAs substrates using defect reduction technique.
