Snake-like light beam propagation in multimode periodic segmented waveguide

Not Accessible

Your library or personal account may give you access

Abstract

In this article it is shown that for specific initial conditions an input beam injected in a multimode periodic segmented waveguide does not diffract and remains collimated all along the waveguide, whereas a speckle-like pattern is expected at the output of a multimode structure. This nonintuitive behavior can be explained with the help of ray and wave chaos properties. A modal analysis developed in this article reveals that this nondiffractive beam regime is due to a specific superposition of modes with regularly spaced propagation constants. A discrepancy with the commonly used equivalent continuous waveguide model is also identified.
