Simultaneous microscopic imaging of thickness and refractive index of thin layers by heterodyne interferometric reflectometry (HiRef)

Alexander Nahmad-Rohen, David Regan, Paola Borri +1

The detection of spatial or temporal variations in very thin samples has important applications in the biological sciences. For example, cellular membranes exhibit changes in lipid…

A model for the complex reflection coefficient of a collection of parallel layers

Alexander Nahmad-Rohen, Wolfgang Langbein

Reflectometry is a technique that uses the light reflected by a sample to determine properties of the sample. Interferometric reflectometry uses interference between two beams, one…

Resonant-state expansion applied to three-dimensional open optical systems: A complete set of static modes

S. V. Lobanov, W. Langbein, E. A. Muljarov

We present two alternative complete sets of static modes of a homogeneous dielectric sphere, for their use in the resonant-state expansion (RSE), a rigorous perturbative method in…

Structure and zero-dimensional polariton spectrum of natural defects in GaAs/AlAs microcavities

Joanna M Zajac, Wolfgang Langbein

We present a correlative study of structural and optical properties of natural defects in planar semiconductor microcavities grown by molecular beam epitaxy, which are showing a lo…
