Abstract
An optical functioning element comprising: an optical functional element having a layer-stacked structure including a crystalline substance layer; a substrate for mounting the optical functional element; and an epitaxial growth layer of the crystalline substance formed between the optical functional element and the substrate. The substrate becomes transparent with respect to the light accessible to the optical functional element so that it becomes possible to optically access the functional element from both sides of the substrate without partly removing the substrate for passing through the light.
