Abstract
An ESD protection device for an electro-optical device may include an optical waveguide segment being in semiconductor material and including a central zone of a first conductivity type, and first and second wings of a second conductivity type different from the first conductivity type and being integral with the central zone. The ESD protection device may include a first conduction terminal on the first wing for defining a first protection terminal, a second conduction terminal on the second wing for defining a second protection terminal, and a resistive contact structure of the first conductivity type having a transverse arm integral with the central zone, and an end in ohmic contact with the first conduction terminal, the resistive contact structure being electrically insulated from the first wing.
