Claim 11:
12. A Gunn diode, comprising:
a first contact layer (110) and a second contact layer (120);
an active layer (130) based on a gallium nitride (GaN) semiconductor material which is formed between the first contact layer (110) and the second contact layer (120);
a substrate (140) on which the active layer (130) is formed with the first contact layer (110) and the second contact layer (120); and
an optical input (150) for a laser (50) in order to facilitate or trigger a charge carrier transfer between extrema (210, 220) of the energy bands of the active layer (130) by means of laser irradiation,
wherein the optical input (150) is formed by a material that is transparent for the laser for at least one of the following components:
the first contact layer (110),
the second contact layer (120),
a passivation layer (160) arranged in such manner that the active layer (130) is formed with the first contact layer (110) and the second contact layer (120) between the passivation layer (160) and the substrate (140).
