Direct measurement of second-order coupling in a waveguide lattice
Robert Keil, Benedikt Pressl, René Heilmann +3
We measure the next-nearest-neighbour coupling in an array of coupled optical waveguides directly via an integrated eigenmode interferometer. In contrast to light propagation exper…
Obtaining tight bounds on higher-order interferences with a 5-path interferometer
Thomas Kauten, Robert Keil, Thomas Kaufmann +3
Within the established theoretical framework of quantum mechanics, interference always occurs between pairs of trajectories. Higher order interferences with multiple constituents a…
Modally Resolved Fabry-Perot Experiment with Semiconductor Waveguides
B. Pressl, T. Günthner, K. Laiho +5
Based on the interaction between different spatial modes, semiconductor Bragg-reflection waveguides provide a highly functional platform for non-linear optics. Therefore, the contr…
