Abstract: Variable line spacing (VLS) blazed gratings were fabricated on silicon substrates using direct laser lithography and anisotropic wet etching. The grating parameters were monitored during fabrication using scanning electron microscopy and atomic force microscopy. The paper reports on the fabrication details and characteristics of VLS-grating prototypes with different blaze angles for a solar-blind UV polychromator.
Keywords: Si diffraction grating, variable line spacing grating, blaze angle, triangle line profile, atomic force microscopy, scanning electron microscopy, UV.
