Wavelength division multiplexing and de-multiplexing system

   
   

A multiplexing and de-multiplexing system that may both use the same wavelength division multiplexing (WDM) device. For multiplexing, light sources provide a plurality of light beams having different wavelengths and the WDM forms a single light beam. For de-multiplexing, a light source provides a light beam having a plurality of different light wavelengths and the WDM forms a plurality of output light beams each having respective of the wavelengths. The WDM devices may particularly be formed from optically multi-dimensional planar gratings and cubical gratings which may diffract single wavelengths, sets of wavelengths, and ranges of wavelengths each with respect to one optical dimension present. The gratings may be discrete or integrated in the multiplexing or the de-multiplexing devices. Complex embodiments of the multiplexing system, such as an interleaver, and complex embodiments of the de-multiplexing system, such as a de-interleaver, can be formed using blocks of the gratings.

Um sistema multiplexing e de-multiplexing que possa ambos usar o mesmo dispositivo multiplexing de divisão de wavelength (WDM). Para multiplexing, as fontes claras fornecem um plurality dos feixes luminosos que têm wavelengths diferentes e o WDM dá forma a um único feixe luminoso. Para de-multiplexing, uma fonte clara fornece um feixe luminoso que tem um plurality de wavelengths claros diferentes e o WDM dá forma a um plurality de feixes luminosos da saída cada um que tem respectivo dos wavelengths. Os dispositivos do WDM podem particularmente ser dados forma dos gratings planar ótica multi-dimensional e dos gratings cúbicos que podem diffract únicos wavelengths, jogos dos wavelengths, e escalas dos wavelengths cada uma com respeito a um presente ótico da dimensão. Os gratings podem ser discretos ou integrados nos dispositivos multiplexing ou de-multiplexing. As incorporações complexas do sistema multiplexing, tais como um interleaver, e as incorporações complexas do sistema de-multiplexing, tais como um de-interleaver-interleaver, podem ser dadas forma usando blocos dos gratings.
