Abstract: The present invention relates to the transmission of optical signals, and more particularly to wavelength division multiplexers and demultiplexers for optical signals. A wavelength division multiplexer device for use in an optical transmission system comprises a light input, one or more lenses, a substrate, one or more holographic optical elements, and two or more light outputs. The light input, the substrate, and the one or more lenses direct a light beam through the device. The one or more holographic optical elements act as transmission diffraction gratings and spatially separate the input light beam into dispersed light beams. Each light output receives one of the dispersed light beams. Multiple holographic optical elements may be stacked upon one another or separated by a substrate. Additionally, the substrate may comprise edges or parts that are beveled. Finally, the elements of the present invention may be rigidly coupled to each other, without intervening air space.

Abstract: A combined multiplexer/demultiplexer for use in optical communication systems is disclosed. The combined multiplexer/demultiplexer includes a plurality of waveguide arrays and a plurality of signal carriers, each disposed substantially symmetrically about an optical axis of the device. In operation, a signal carrier emits a multiple wavelength optical signal that is received and directed to a dispersion apparatus by a light focusing device. The dispersion apparatus diffracts the optical signal into selected spectral components and reflects the spectral components back to the waveguide arrays through the light focusing device. The signal processing, such as multiplexing and demultiplexing, performed by each waveguide array depends on their configuration. The waveguide arrays may be configured to substantially simultaneously multiplex and/or demultiplex the spectral components.
