Wavefront shaping with disorder-engineered metasurfaces
Mooseok Jang,Yu Horie,Atsushi Shibukawa,Joshua Brake,Yan Liu,Seyedeh Mahsa Kamali,Amir Arbabi,Haowen Ruan,Andrei Faraon,Changhuei Yang +9 more
TL;DR: In this paper, a disorder-engineered metasurface was proposed for wavefront shaping with disordered media, where the disorder is specifically designed so its exact input-output characteristics are known a priori and can be used with only a few alignment steps.

Complex wavefront engineering with disorder-engineered metasurfaces
Mooseok Jang,Yu Horie,Atsushi Shibukawa,Joshua Brake,Yan Liu,Seyedeh Mahsa Kamali,Amir Arbabi,Haowen Ruan,Andrei Faraon,Changhuei Yang +9 more
TL;DR: In this paper, the disorder is specifically designed so that its exact characteristics are known, resulting in an a priori determined transmission matrix that can be utilized with only a few alignment steps.
Journal ArticleDOI
Optical focusing deep inside dynamic scattering media with near-infrared time-reversed ultrasonically encoded (TRUE) light
TL;DR: By imaging a target, the first focusing of diffuse light inside a dynamic scattering medium containing living tissue is demonstrated, an important step towards in vivo deep tissue noninvasive optical imaging, optogenetics and photodynamic therapy.
Journal ArticleDOI
Time-reversed adapted-perturbation (TRAP) optical focusing onto dynamic objects inside scattering media
TL;DR: By time-reversing the perturbed component of the scattered light adaptively, it is shown that it is possible to focus light to the origin of the perturbation by employing intrinsic dynamics as guide stars.
Journal ArticleDOI
Focusing light inside dynamic scattering media with millisecond digital optical phase conjugation.
TL;DR: This work develops a simpler but faster DOPC system that focuses light not only through, but also inside scattering media, and is an important step toward in vivo deep-tissue non-invasive optical imaging, manipulation, and therapy.
