Coherent Injection of Light into an Absorbing Scattering Medium with a Microscopic Pore

We demonstrate that interplay between absorption and scattering in a dielectric medium with a microscopic pore gives rise to eigenchannels concentrated in the pore. Such a circumvention of attenuation leads to high transmission. By exciting such eigenchannels in a disordered nanophotonic system with a wavefront shaping technique, we experimentally confirm enhanced injection at depths exceeding the limiting length scales set by scattering, absorption, and diffraction.
