摘要: An optical structure includes a substrate having two side surfaces. A first layer of high refractive index material is formed on the substrate. A sacrificial layer is formed on the first layer. A second layer of high refractive index material is formed on the sacrificial layer. At a predefined temperature the sacrificial layer is evaporated, thus forming an air gap between the first layer and the second layer.
