Sub-micrometer Nanostructure-based RGB Filters for CMOS Image Sensors
Jonas Berzinš, Stefan Fasold, Thomas Pertsch +2
Digital color imaging relies on spectral filters on top of a pixelated sensor, such as a CMOS image sensor. An important parameter of imaging devices is their resolution, which dep…
All-dielectric resonant meta-optics goes active
Isabelle Staude, Thomas Pertsch, Yuri Kivshar
All-dielectric resonant nanophotonics is a rapidly developing research field driven by its exceptional application potential for low-loss nanoscale metadevices. The tight confineme…
Using effective medium theories to design tailored nanocomposite materials for optical systems
Daniel Werdehausen, Isabelle Staude, Sven Burger +4
Modern optical systems are subject to very restrictive performance, size and cost requirements. Especially in portable systems size often is the most important factor, which necess…
Common pulse retrieval algorithm: a fast and universal method to retrieve ultrashort pulses
Nils C. Geib, Matthias Zilk, Thomas Pertsch +1
We present a common pulse retrieval algorithm (COPRA) that can be used for a broad category of ultrashort laser pulse measurement schemes including frequency-resolved optical gatin…
Design rules for customizable optical materials based on nanocomposites
Daniel Werdehausen, Isabelle Staude, Sven Burger +4
Nanocomposites with tailored optical properties can provide a new degree of freedom for optical design. However, despite their potential these materials remain unused in bulk appli…
Wavelength-scale ptychographic coherent diffractive imaging using a high-order harmonic source
Getnet K. Tadesse, Wilhelm Eschen, Robert Klas +9
Ptychography enables coherent diffractive imaging (CDI) of extended samples by raster scanning across the illuminating XUV/X-ray beam thereby generalizing the unique advantages of…
