Abstract: An optical component serves as a nonlinear photodetector for generating a nonlinear electrical signal. The component comprises a first electrically conductive layer, a second electrically conductive layer and an absorption layer. The absorption layer is arranged between the first and the second electrically conductive layer and has a layer thickness of at least 500 nm. The electrical signal is generated by the component by applying a voltage at the component and irradiating the component with electromagnetic radiation in a first wavelength range (λ1) with a radiation intensity of less than 10 nW/mm2 and also irradiating the optical component with electromagnetic radiation in a second wavelength range (λ2) that is different from the first wavelength range (λ1) and a radiation intensity of less than 100 nW/mm2.
