摘要：
A polarization-independent wavelength demultiplexing apparatus for demultiplexing a light beam of at least one predetermined wavelength, includes a first demultiplexer for demultiplexing the light beam at a predetermined wavelength to obtain a component of the light beam in a first polarization state and second demultiplexer for demultiplexing the light beam at the predetermined wavelength to obtain a component of the light beam in a second polarization state, different from the first polarization state. The first demultiplexer and the second demultiplexer are arranged in a serial manner or in a parallel manner with respect to light transmitted through the demultiplexing structure.
