摘要： A tunable demultiplexer accepts an input optical signal that has multiple spectral bands and provides multiple output signals. Each of the output signals corresponds to a selected one of the spectral bands. The tunable demultiplexer has at least one wavelength routing element and at least one optical arrangement disposed to exchange light with the wavelength routing element. The wavelength routing element is of the type adapted for selectively routing wavelength components of a first optical signal onto multiple second optical signals according to a configurable state.

摘要： The present invention relates to a numerous user laser communications optical system. Numerous optical signals comprising a number of channels are simultaneously received and demultiplexed (and/or multiplexed and transmitted) at a numerous access communication device. The numerous access communication device may comprise multiple stages that each include a multiple order waveplate and a polarizing beam splitter. The multiple order waveplate is configured so that it retards a first electrical field component of signals corresponding to certain channels in a frequency grid in an integer multiple of wavelengths with respect to a second electrical field component, and retards a first electrical field component of signals corresponding to other channels in the frequency grid in an integer multiple of wavelengths plus one-half a wavelength with respect to a second electrical field component. Separation can then be performed on the basis of the resulting opposite polarization.
