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
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
1.5-mm Indium Phosphide-Based Quantum Dot Lasers and Optical Amplifiers: The Impact of Atom-Like Optical Gain Material for Optoelectronics Devices
Sven Bauer,Vitalii Sichkovskyi,Ori Eyal,Tali Septon,Annette Becker,Igor Khanonkin,Gadi Eisenstein,Johann Peter Reithmaier +7 more
TL;DR: In this article, a bottom-up approach of strain-driven, self-organized epitaxial quantum dot growth was proposed to produce nanoscale species on very large surfaces and interface areas, resulting in the accumulation of a large defect density within the active region and the domination of nonradiative carrier recombination mechanisms.
Narrow-linewidth 1.5 μm quantum dot distributed feedback lasers for next generation coherent communication
Annette Becker,Tali Septon,Sutapa Ghosh,Marco Bjelica,Vitalii Sichkovskyi,Anna Rippien,Florian Schnabel,Bernd Witzigmann,Gadi Eisenstein,Johann Peter Reithmaier +9 more
TL;DR: In this paper, a quantum dot (QD) material with five QD layers in the active region was used to fabricate distributed feedback (DFB) lasers with a cavity length of 1.5 mm.
Proceedings ArticleDOI
Narrow-linewidth 1.5μm quantum dot distributed feedback lasers
Annette Becker,Vitalii Sichkovskyi,Marko Bjelica,Ori Eyal,Philipp Baum,Anna Rippien,Florian Schnabel,Bernd Witzigmann,Gadi Eisenstein,Johann Peter Reithmaier +9 more
TL;DR: In this article, the impact of different gain materials consisting of different numbers of QD layers on the linewidth of distributed feedback (DFB) lasers was investigated and showed an unambiguous dependence on the layer design.
