    摘要: An optical component (10) for modulating a light field (1) incident on the optical component (10), in particular for modulating at least one of amplitude and phase of the light field (1) in dependency on the intensity (I) thereof, comprises a stack (11) of refractive layers (12, 13) being arranged on a substrate (14), being made of materials having a third-order nonlinearity, and having alternatingly varying refractive indices (n), including a linear contribution (no) and a non-linear contribution (n 2 ), and determining reflectance and transmittance spectra of the optical component, wherein the refractive layers (12, 13) are configured such that reflectance and transmittance of the optical component have a Kerr effect based dependency on the intensity (I) of the incident light field with n = no + I·n 2 , and the refractive layers (12, 13) are made of at least one of dielectric and semiconductor layers, wherein the non-linear contribution (n 2 ) is below 10 -12 cm 2 /W. Furthermore, a resonator device including the optical component, a method of modulating a light field using the optical component and a method of manufacturing the optical component are described.
