Interference in Diamond Membranes for Brighter Defects Thin film interference in a wedge-shaped diamond membrane produces thickness-dependent reflection and absorption across the visible spectrum, creating a rainbow-like pattern across the gradient. This optical effect modulates and enhances the emission from embedded silicon vacancy centers by up to 96-fold, offering a route to cavity-free control of solid-state quantum emitters.
