From Planar to 3D Nanophotonic Lenses: Advancing Design, Fabrication, and Applications

Laser &Photonics Reviews, EarlyView.
Three‐dimensional nanophotonic lenses are enabled by an integrated workflow that links design parameterization, full‐wave electromagnetic simulation, computational optimization, and freeform fabrication. This Review summarizes how these tools expand optical design freedom beyond a single patterned plane by enriching the local meta‐atom response and ...

Improving ARTs: Microfluidics as a Tool for Sperm Selection

Andrology, EarlyView.
ABSTRACT Sperm selection is a critical step in assisted reproductive technology (ART), as sperm quality directly influences embryo quality. In vivo, the female reproductive tract imposes several physical and physiological barriers that favors only the most optimal spermatozoa reaching the fertilization site.

Holographic fluorescence microscopy with incoherent digital holographic adaptive optics

Journal of Biomedical Optics, 2015
Introduction of adaptive optics technology into astronomy and ophthalmology has made great contributions in these fields, allowing one to recover images blurred by atmospheric turbulence or aberrations of the eye. Similar adaptive optics improvement in microscopic imaging is also of interest to researchers using various techniques.
