Microdroplet Actuation via Light Line Optoelectrowetting (LL-OEW)
International Journal of Analytical Chemistry, 2021 Meanwhile, electrowetting-on-dielectric (EWOD) is a well-known phenomenon, even often exploited in active micro-optics to change the curvature of microdroplet lenses or in analytical chemistry with digital microfluidics (DMF, lab on a chip 2.0) to move ...

Nano-imprinted subwavelength gratings as polarizing beamsplitters
Journal of the European Optical Society-Rapid Publications, 2021 Polarizing beamsplitters have numerous applications in optical systems, such as systems for freeform surface metrology. They are classically manufactured from birefringent materials or with stacks of dielectric coatings. We present a binary subwavelength-
