Ge2Sb2Se4Te‐Based Optical Switch with Ultra‐High Contrast Ratio by Multilayer Fabry–Perot Cavity

Ge2Sb2Se4Te‐Based Optical Switch with Ultra‐High Contrast Ratio by Multilayer Fabry–Perot Cavity

Abstract Optical switches always desire a high contrast ratio in optical logic circuits and optical communication devices. Although phase change materials are widely applied to design optical switches for their rapid phase change, the high contrast ratio is still hardly achieved for the intrinsic lo...
