Method and apparatus for wavelenght multiplexing/demultiplexing |
摘要 |
A wavelength division multiplexing/demultiplexing device is presented utilizing a polarization-based filter to obtain a flat-top filter response which can be utilized to create a flat-top slicer which separates out odd and even wavelengths, or upper and lower channels of an input signal. The polarization-based filter provides superior peak flatness and isolation for narrow channel spacings over what can be obtained in traditional interferometric devices. The flat-top slicer can be used as the first stage of a cascade of WDM devices in which following stages can be based on polarization-based filters or traditional interferometric WDM devices, which are adequate due to the increased channel spacing obtained in the first stage of the cascade. |
