ABSTRACT:
A device for emitting optical radiation is integrated on a substrate of semiconductor material. The device includes an active layer having a main area for generating radiation, and first and second electro-conductive layers having an electric signal that generates an electric field to which an exciting current is associated. In the device, a dielectric region is formed between the first and second layers to space peripheral portions of the first and second layers so that the electric field in the main area is higher than the electric field between the peripheral portions, thereby facilitating generation of the exciting current in the main area. A method of manufacturing is also disclosed.
