Sensitive control of broad-area semiconductor lasers by cavity shape
Kyungduk Kim, Stefan Bittner, Yuhao Jin +5
The ray dynamics of optical cavities exhibits bifurcation points: special geometries at which ray trajectories switch abruptly between stable and unstable. A prominent example is t…

Universal sensitivity of speckle intensity correlations to wavefront change in light diffusers
KyungDuk Kim, HyeonSeung Yu, KyeoReh Lee +1
Here, we present a concept based on the realization that a complex medium can be used as a simple interferometer. Changes in the wavefront of an incident coherent beam can be retri…
