Mixture and distribution process and device

摘要

When mixing polychromatic light, light with only one wave length is fed to each element in a selective chain to form a partial spectrum. When distributing polychromatic light, one wave length is filtered out of each element. After reflection the remaining spectrum is fed to the next element to be decomposed further. A chain of photonic crystals is used for mixing and distributing. A wave length selective coupler/decoupler is allocated to each crystal.
