Paper Abstract
In the paper an approach to improve diffraction efficiency of a transmission concave holographic grating for a flat-field
spectrograph is presented. The proposed method is based on numerical optimization of a merit function. Each iteration of
the procedure includes definition of the grating recording parameters and the spectrum position from conditions of
aberration correction, estimation of the diffraction efficiency by means of the Kogelnik coupled-wave theory equations,
and checking boundary conditions. It’s shown on a certain example that the technique allows to obtain high spectral
resolution and increase the diffraction efficiency. Modeling results and comparison with accurate RCWA computation
are provided as well.
