Microscopic Theory for the Incoherent Resonant and Coherent Off-Resonant Optical Response of Tellurium
S. C. Liebscher, M. K. Hagen, J. Hader +2
An based fully microscopic approach is applied to study the nonlinear optical response of bulk Tellurium. The structural and electronic properties are calcula…
Mode-locking in vertical external-cavity surface-emitting lasers with type-II quantum-well configurations
I. Kilen, S. W. Koch, J. Hader +1
A microscopic study of mode-locked pulse generation is presented for vertical external-cavity surface-emitting lasers utilizing type-II quantum well configurations. The coupled Max…
Non-equilibrium dynamics in the dual-wavelength operation of Vertical external-cavity surface-emitting lasers
I. Kilen, J. Hader, S. W. Koch +1
Microscopic many-body theory coupled to Maxwell's equation is used to investigate dual-wavelength operation in vertical external-cavity surface-emitting lasers. The intrinsically d…
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…
