ABSTRACT:
An optoelectronic multi-wavelength component is described for n waveguides with optical feedback gratings arranged side by side laterally to have different characteristic wavelengths. The multi-wavelength component is based on at least two optical waveguides arranged on a substrate so they intersect the grating lines of one or more grating fields at different angles. The grating lines of the feedback grating run at a tilted angle relative to a preferential direction. The angles between each individual waveguide and the grating lines of the respective grating are in the range between 40.degree. and 140.degree.. A controlled change in the effective corrugation period from one waveguide to the next is achieved by means of the individual dimensioning of the tilt angle between the waveguide and the grating lines of the respective feedback grating. The solution is used in photonic components that work on different waveguide channels and are based on DFB or DBR gratings or sampled gratings.
