Paper Abstract
Volume phase holographic gratings (VPHGs) are becoming fundamental dispersing elements in astronomical
instrumentation. Here it will be described the efficiency behavior of such dispersing elements at high diffraction orders
for understanding the possible use as echelle gratings. The efficiency is calculated based on RCWA analysis and
different parameters are changed/optimized, i.e film thickness, refractive index modulation and profile. The results show
that the VPHGs are not suitable for working at high orders in the classical configurations.
