Abstract
An optical component (7) is described in which the frequency of electromagnetic radiation is raised and which comprises a non-linear optical medium and an optical modulation structure (21) so as to compensate for the wavelength dispersion in the non-linear optical material so that there is phase matching. By providing a satellite layer (15) having a high refractive index proximate to the modulation structure (21), the wavelength at which phase matching occurs is not critical for the layer thickness of the non-linear optical medium. An opto-electronic device (1) for raising the frequency of electromagnetic radiation, comprising such a component (7) as a frequency-raising element is also described.
