Abstract

We realize experimentally a true reflectionless potential, which facilitates nonresonant unity transmission for all incident waves and at the same time supports localized modes. We utilize arrays of evanescently coupled optical waveguides, where a particular modulation of the transverse waveguide separations provides a physical realization of reflectionless Ablowitz-Ladik soliton potentials.

A light beam passes through it

Published 12 May 2011

Experiments confirm a decades-old prediction that carefully tailoring the shape of a barrier lets light of many colors pass through it without reflection.
