Abstract:
1. A flexible waveguide capable of propagating and emitting light, comprising: a flexible multilayered material shaped as a sheet and having a plurality of particles distributed in said flexible material in an increasing concentration such that a first portion of the light is scattered by said particles and emitted through at least a portion of a surface of said sheet to provide a light gradient emanating from said surface; wherein at least one layer of said multilayered material is configured such that light is emitted through one surface of said sheet while another surface remains opaque; wherein said flexible material comprises a first layer having a first refractive index, and a second layer being in contact with said first layer and having a second refractive index being larger that said first refractive index and wherein said particles are distributed in said first layer and said second layer.
