  • Optical component for modulating a light field and applications thereof
    Patent number: 10191352
    Abstract: Optical component (10) for modulating light field (1) incident thereon, particularly amplitude and/or phase in dependency on intensity (I) thereof, includes stack (11) of refractive layers (12, 13) on substrate (14), made of materials having third-order nonlinearity, and having alternatingly varying refractive indices (n), including linear contribution (n0) and non-linear contribution (n2), and determining reflectance and transmittance spectra of the optical component, wherein refractive layers (12, 13) are configured such that reflectance and transmittance of the optical component have a Kerr effect based dependency on intensity (I) of the incident light field with n=n0+I·n2, and refractive layers (12, 13) are made of at least one of dielectric and semiconductor layers, wherein non-linear contribution (n2) is below 10?12 cm2/W. 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.
