Abstract
An optoelectronic device has an epitaxial layer structure that has a substrate and a first layer formed adjacent to the substrate. The first layer may, for example, form a contact layer. A second layer is formed adjacent to the first layer. The second layer forms a selectively optically varying layer, so that during a first state the second layer is optically absorbing and during a second state the layer is optically transparent. A third layer is formed adjacent to the second layer. A fourth layer is formed adjacent to the third layer. The fourth layer is an optically transparent layer. An optoelectronic device and an electronic device may be formed on the same substrate that share the same layers. The layers used depends upon the devices formed.
