  • Device and method for multiplexing and/or demultiplexing optical signals of a plurality of wavelengths
    Publication number: 20030002101
    Abstract: A device and a method for multiplexing and/or demultiplexing optical signals of a plurality of wavelengths. The optical signals of the various wavelengths are combined or separated in a wavelength-selective manner. To combine or separate the individual wavelengths, only one wavelength-selective filter is used, and the optical signals are routed in such a way that they repeatedly strike the wavelength-selective filter at respectively different angles. The optical signals of only one specific wavelength are coupled in or out for each angle.
