Symmetries and optical transitions of hexagonal quantum dots in GaAs/AlGaAs nanowires
Guro K. Svendsen, Johannes Skaar, Helge Weman +1
We investigate the properties of electronic states and optical transitions in hexagonal GaAs quantum dots within AlGaAs nanowires. Such dots are particularly interesting due to the…
Reciprocity and the scattering matrix of waveguide modes
Guro K. Svendsen, Magnus W. Haakestad, Johannes Skaar
The implications of the Lorentz reciprocity theorem for a scatterer connected to waveguides with arbitrary modes, including degenerate, evanescent, and complex modes, are discussed…
Investigations of Bragg reflectors in nanowire lasers
Guro Kristin Svendsen, Helge Weman, Johannes Skaar
The reflectivity of various Bragg reflectors in connection to waveguide structures, including nanowires, has been investigated using modal reflection and transmission matrices. A s…
Model for reflection and transmission matrices of nanowire end facets
Guro K. Svendsen, Helge Weman, Johannes Skaar
Nanowires show a large potential for various electrooptical devices, such as light emitting diodes, solar cells and nanowire lasers. We present a direct method developed to calcula…
