Topology optimization of blazed metasurface gratings for high-efficiency spectrographs
A topology optimized metasurface grating is presented, designed using a 3D, in-house developed Finite Element model. It is manufacturable and exhibits nearly 60% of average diffraction efficiency on the −1st order between 400 and 1500 nm.
