APPARATUS FOR WAVELENGTH DEMULTIPLEXING USING A MULTI-CAVITY ETALON |
摘要 |
A wavelength division demultiplexing device is presented utilizing a polarization-based filter or a multi-cavity etalon (700) (e.g., a multi-cavity Fabry-Perot etalon) to obtain a flat-top filter response which can be utilized to create a flat-top slicer (400) which separates out odd and even wavelengths, or upper and lower channels of an input WDM signal. The flat-top slicer can be used as the first stage of a cascaded network of wavelength demultiplexers (410a, 410b, 420a-420d) in which following stages can be based on polarization-based filters, multi-cavity etalons, or other interferometric WDM devices, which are adequate due to the increased channel spacing obtained in the first stage of the network.
