A spectral light division and recombination configuration has 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 has a polarization-selective...http://www.google.com.au/patents/US6550919?utm_source=gb-gplus-sharePatent US6550919 - Spectral light division and recombination configuration as well as process for the spectrally selective modulation of light
