<p>In a wavelength-selective optical signal processing device, an outcoupling filter for decomposing an incoming wavelength multiplex comprising a plurality of channels at different wavelengths into a first and a second group of channels and an incoupling filter for combining the first group after having passed through a processing unit and the second group into an outgoing wavelength multiplex are combined in a continuous wavelength-selective reflecting structure.</p> |
