Abstract

Extracting the light trapped in a waveguide, or the opposite effect of trapping light in a thin region and guiding it perpendicular to its incident propagation direction, is essential for optimal energetic performance in illumination, display or light harvesting devices. Here we demonstrate that the paradoxical goal of letting as much light in or out while maintaining the wave effectively trapped can be achieved with a periodic array of interpenetrated bers forming a photonic ber plate. Photons entering perpendicular to that plate may be trapped in an intermittent chaotic trajectory, leading to an optically ergodic system. We fabricated such a photonic ber plate and showed that for a solar cell incorporated on one of the plate surfaces, light absorption is greatly enhanced. Conrming this, we found the unexpected result that a more chaotic photon trajectory reduces the production of photon scattering entropy.
