Wavefront shaping with disorder-engineered metasurfaces [PDF]
Nature Photonics, 2018 Recently, wavefront shaping with disordered media has demonstrated optical manipulation capabilities beyond those of conventional optics, including extended volume, aberration-free focusing and subwavelength focusing. However, translating these capabilities to useful applications has remained challenging as the input-output characteristics of the ...

Coupling of energy into the fundamental diffusion mode of a complex nanophotonic medium [PDF]
New Journal of Physics, 2016 We demonstrate experimentally that optical wavefront shaping increases light coupling into the fundamental diffusion mode of a scattering medium. The total energy density inside a scattering medium of zinc oxide nanoparticles was probed by exciting ...

Measuring optical transmission matrices by wavefront shaping
Optics Express, 2015 We introduce a simple but practical method to measure the optical transmission matrix (TM) of complex media. The optical TM of a complex medium is obtained by modulating the wavefront of a beam impinging on the complex medium and imaging the transmitted ...
