Journal ArticleDOI
High-power picosecond and femtosecond pulse generation from a two-section mode-locked quantum-dot laser
Edik U. Rafailov,Maria Ana Cataluna,W. Sibbett,N. D. Il’inskaya,Yu. M. Zadiranov,A. E. Zhukov,Victor M. Ustinov,D.A. Livshits,A. R. Kovsh,Nikolai N. Ledentsov +9 more
TL;DR: In this paper, a two-section quantum-dot laser that produces output powers up to 45 mW at 1260 nm was demonstrated. The pulse duration could be varied from 2 ps to as short as 400 fs at the 21 GHz pulse repetition rate.
Journal ArticleDOI
High power temperature-insensitive 1.3 µm InAs/InGaAs/GaAs quantum dot lasers
S. S. Mikhrin,A. R. Kovsh,Igor Krestnikov,A. V. Kozhukhov,D.A. Livshits,N. N. Ledentsov,Yu. M. Shernyakov,Innokenty I. Novikov,Mikhail V. Maximov,V. M. Ustinov,Zh. I. Alferov +10 more
TL;DR: In this paper, GaAs-based broad area (100 µm) 1.3 µm quantum dot (QD) laser with high CW output power (5 W) and wall-plug efficiency (56%) was demonstrated.
Journal ArticleDOI
InAs/InGaAs/GaAs quantum dot lasers of 1.3 [micro sign]m range with high (88%) differential efficiency
A. R. Kovsh,Nikolay A. Maleev,A. E. Zhukov,S. S. Mikhrin,A. P. Vasil’ev,Yu. M. Shernyakov,Mikhail V. Maximov,D.A. Livshits,V. M. Ustinov,Zh. I. Alferov,N. N. Ledentsov,Dieter Bimberg +11 more
TL;DR: In this article, multiple layers (up to 10) of InAs/InGaAs/GaAs quantum dots were used to enhance the optical gain of quantum dot laser emitting around 1.3 µm.
Journal ArticleDOI
Continuous-wave operation of long-wavelength quantum-dot diode laser on a GaAs substrate
A. E. Zhukov,A. R. Kovsh,Victor M. Ustinov,Yu. M. Shernyakov,S. S. Mikhrin,N. A. Maleev,E.Yu. Kondrat'eva,D.A. Livshits,Mikhail V. Maximov,B. V. Volovik,D. A. Bedarev,Yu. G. Musikhin,Nikolai N. Ledentsov,P. S. Kop’ev,Zh. I. Alferov,Dieter Bimberg +15 more
TL;DR: In this article, a diode laser based on self-organized quantum dots (QD's) on a GaAs substrate is demonstrated, where multiple stacking of InAs QD planes covered by thin InGaAs layers allows to prevent gain saturation and achieve long-wavelength lasing with low threshold current density (90-105 A/cm/sup 2/) and high output power (2.7 W) at 17/spl deg/C heatsink temperature.
Journal ArticleDOI
Quantum dot laser with 75 nm broad spectrum of emission.
TL;DR: A significant overlap and approximate equalization of the ground-state and the excited-state emission bands in the laser's spectrum is achieved by means of intentional inhomogeneous broadening of the quantum dot energy levels.
