Journal ArticleDOI
Large linewidth reduction in semiconductor lasers based on atom-like gain material
Tali Septon,Annette Becker,Sutapa Gosh,Gal Shtendel,Vitalii Sichkovskyi,Florian Schnabel,Anna Sengül,Marko Bjelica,Bernd Witzigmann,Johann Peter Reithmaier,Gadi Eisenstein +10 more
TL;DR: In this article, the spectral and power characteristics of a single-mode InAs/AlGaInAs/InP QD distributed feedback laser operating at 1.5μm were described.
Journal ArticleDOI
Rabi oscillations and self-induced transparency in InAs/InP quantum dot semiconductor optical amplifier operating at room temperature
TL;DR: Direct observations of Rabi oscillations and self-induced transparency in a quantum dot optical amplifier operating at room temperature and a numerical model which solves the Maxwell and Schrödinger equations and accounts for the inhomogeneously broadened nature of the quantum dot gain medium are reported.
Journal ArticleDOI
High-gain wavelength-stabilized 1.55 μm InAs/InP(100) based lasers with reduced number of quantum dot active layers
TL;DR: In this article, the effect of the number of InAs/InP quantum dot layers (QDLs) on the static parameters of 1.55μm emitting lasers was studied in the range of 1-3 QDLs.
Journal ArticleDOI
Widely tunable narrow-linewidth 1.5 μm light source based on a monolithically integrated quantum dot laser array
Annette Becker,Vitalii Sichkovskyi,Marko Bjelica,Anna Rippien,Florian Schnabel,M. Kaiser,Ori Eyal,Bernd Witzigmann,Gadi Eisenstein,Johann Peter Reithmaier +9 more
TL;DR: In this article, a monolithically integrated widely tunable narrow-linewidth light source was realized on an InP-based quantum dot (QD) gain material, which enabled standalone distributed feedback (DFB) lasers with intrinsic linewidths as low as 110 kHz.
Journal ArticleDOI
Temperature-Insensitive High-Speed Directly Modulated 1.55- $\mu \text{m}$ Quantum Dot Lasers
S. Banyoudeh,A. Abdollahinia,Ori Eyal,Florian Schnabel,Vitalii Sichkovskyi,Gadi Eisenstein,Johann Peter Reithmaier +6 more
TL;DR: In this article, the modulation properties and temperature stability of short cavity ridge waveguide lasers based on high-quality InAs quantum dots exhibiting a total modal gain of ~90 cm at room temperature and up to 36 mW are reported.
