Abstract: It is described a device (100) for emitting optical radiation integrated on a substrate (1) of semiconductor material, comprising:
- an active means layer (10) comprising a main area (30) generating the radiation,
- a first (7) and second (11) electro-conductive layers for an electric signal generating an electric field to which an exciting current is associated,
- a dielectric region (8') included between said first (7) and second (11) layers in order to space corresponding peripheral portions of said first (7) and second (11) layers from each other such that the electric field being present in the main area is higher than the one being present between said peripheral portions thus facilitating a corresponding generation of the exciting current in the main area (30).
