Low-threshold operation of GaAs-based (GaIn)As/Ga(AsSb)/(GaIn)As W-quantum well lasers emitting in the O-band
Christian Fuchs, Imad Limame, Stefan Reinhard +6
The influence of the growth conditions as well as the device design on the device performance of (GaIn)As/Ga(AsSb)/(GaIn)As "W"-quantum well lasers is investigated. To this purpose…
Temperature-dependent spectral properties of (GaIn)As/Ga(AsSb)/(GaIn)As W-quantum well heterostructure lasers
Christian Fuchs, Ada Baeumner, Anja Brueggemann +7
This paper discusses the temperature-dependent properties of (GaIn)As/Ga(AsSb)/(GaIn)As W-quantum well heterostructures for laser applications based on theoretical modeling as well…
Performance characteristics of low threshold current 1.25-μm type-II GaInAs/GaAsSb W-lasers for optical communications
Dominic A. Duffy, Igor P. Marko, Christian Fuchs +4
Type-II W-lasers have made an important contribution to the development of mid-infrared laser diodes. In this paper, we show that a similar approach can yield high performance lase…
Band Offset in (Ga,In)As/Ga(As,Sb) Heterostructures
S. Gies, M. J. Weseloh, C. Fuchs +5
A series of (Ga,In)As/GaAs/Ga(As,Sb) multi-quantum well heterostructures is analyzed using temperature- and power-dependent photoluminescence (PL) spectroscopy. Pronounced PL varia…
Recombination dynamics of type-II excitons in (Ga,In)As/GaAs/Ga(As,Sb) heterostructures
S. Gies, B. Holz, C. Fuchs +2
(Ga,In)As/GaAs/Ga(As,Sb) multi-quantum well heterostructures have been investigated using continuous wave and time-resolved photoluminescence spectroscopy at various temperatures.…
Gain spectroscopy of a type-II VECSEL chip
Christian Lammers, Markus Stein, Christian Berger +9
Using optical pump-white light probe spectroscopy the gain dynamics is investigated for a VECSEL chip which is based on a type-II heterostructure. The active region the chip consis…
