Organic (opto) electronic materials have received considerable attention due to their
applications in thin-film-transistors, light-emitting diodes, solar cells, sensors, photorefractive …

Coherent optical control within or through scattering media via wavefront shaping has seen
broad applications since its invention around 2007. Wavefront shaping is aimed at …

Non-invasively focusing light into strongly scattering media, such as biological tissue, is
highly desirable but challenging. Recently, ultrasonically guided wavefront-shaping …

Fluorescence imaging is one of the most important research tools in biomedical sciences.
However, scattering of light severely impedes imaging of thick biological samples beyond …

Focusing light deep inside living tissue has not been achieved despite its promise to play a
central role in biomedical imaging, optical manipulation and therapy. To address this …

Focusing of light in the diffusive regime inside scattering media has long been considered
impossible. Recently, this limitation has been overcome with time reversal of ultrasound …

Wavefront shaping based on digital optical phase conjugation (DOPC) focuses light through
or inside scattering media, but the low speed of DOPC prevents it from being applied to …

Fluorescence imaging has revolutionized biomedical research over the past three decades.
Its high molecular specificity and unrivalled single-molecule-level sensitivity have enabled …

We demonstrate a method for phase conjugating fluorescence. Our method, called
reference free digital optical phase conjugation, can conjugate extremely weak, incoherent …

Focusing light through scattering media has been a longstanding goal of biomedical optics.
While wavefront shaping and optical time-reversal techniques can in principle be used to …
