Nonlinear waves in waveguide networks
Project description
Many wave guides (such as optical fibres) show a Kerr-type effect that leads to nonlinear wave propagation. If the wave guides are coupled at junctions then there is an additional element of complexity due to the non-trivial connectivity of wave guides. In this project the impact of the structure and topology of the network on wave propagation will be studied starting from simple geometries such as a Y-junctions (three waveguides coupled at one junction), a star (many waveguides at one junction), or a lasso (a waveguide that forms a loop and is connected at one point to a second waveguide).
