Abstract:
Spectral light division and recombination configuration with an incident face for light to be divided, at least one emergent face for recombined light and a spectrally selective division and recombination device, the spectrally selective division and recombination device comprising:a polarization-selective division and recombination configuration whereon light of one spectral range (&Dgr;&lgr;3) is at least one of separated from and recombined with, light of other spectral ranges (&Dgr;&lgr;1, &Dgr;&lgr;2); the polarization-selective division and recombination configuration being preceded by a spectrally selective polarization rotator and the spectrally selective polarization rotator being preceded by a broad-band polarizer.
