Index-antiguiding in narrow-ridge GaN-based laser diodes investigated by measurements of the current-dependent gain and index spectra and by self-consistent simulation
Luca Redaelli, Hans Wenzel, Joachim Piprek +6
The threshold current density of narrow (1.5 μm) ridge-waveguide InGaN multi-quantum-well laser diodes, as well as the shape of their lateral far-field patterns, strongly depend on…
Terahertz Conductivity of the Heavy-Fermion State in CeCoIn5
Marc Scheffler, Thomas Weig, Martin Dressel +5
The optical properties of thin films of the heavy-fermion compound CeCoIn5, which were deposited by molecular beam epitaxy onto MgF2 substrates, have been studied at frequencies 7…
Superfluorescent emission in electrically pumped semiconductor laser
D. L. Boiko, X. Zeng, T. Stadelmann +7
We report superfluorescent (SF) emission in electrically pumped InGaN/InGaN QW lasers with saturable absorber. In particular, we observe a superlinear growth of the peak power of S…
Anisotropic optical conductivity of the putative Kondo insulator CeRuSn
V. Guritanu, P. Wissgott, T. Weig +11
Kondo insulators and in particular their non-cubic representatives have remained poorly understood. Here we report on the development of an anisotropic energy pseudogap in the tetr…
