Patterning waveguide coupling constants enables control of Floquet-Bloch waves. This breakthrough allows for light redirection, guiding, focusing, and nonlinear all-optical routing in discrete photonics.

Area of Science:

Photonics and Wave Phenomena
Materials Science and Engineering

Background:

Floquet-Bloch waves propagate freely in homogeneous arrays of coupled waveguides.

To demonstrate how engineered coupling patterns can control light behavior within discrete waveguide arrays.

Main Methods:

Theoretical analysis of Floquet-Bloch wave dynamics in patterned waveguide arrays.
Numerical simulations to visualize and quantify wave manipulation through coupling patterns.

Main Results:

Identified specific coupling patterns that can redirect, guide, and focus Floquet-Bloch waves.
