Nano-structured diffraction gratings as polarizing beam splitters under vertical incidence

Polarizing beam splitters have numerous applications in optical systems, e.g. for the measurement of freeform surfaces. We present a design and manufacturing process for a nanostructured diffraction grating with optimized diffraction efficiencies for TE- and TM-polarization, which acts as a beam spl...

Beschreibung
Zusammenfassung:	Polarizing beam splitters have numerous applications in optical systems, e.g. for the measurement of freeform surfaces. We present a design and manufacturing process for a nanostructured diffraction grating with optimized diffraction efficiencies for TE- and TM-polarization, which acts as a beam splitter over a long range of incidence angles. First measurements confirm a strong difference in diffraction efficiencies.
