Abstract
A component to be used for the frequency-selective modulation and/or for the frequency-selective receiving and demodulation of frequency-division multiplexed optical signals. The component of the present invention includes a waveguide, to which multiplexed optical signals are applied, and at least one further waveguide, running substantially parallel to the waveguide and which is evanescently coupled to the waveguide. The at least one further waveguide is designed as a Bragg resonator, by means of a structuring in the longitudinal direction, and the component further includes at least one semiconductor diode, which is optically coupled to the Bragg resonator.
