ABSTRACT:
A method for wavelength-selective mixing and/or distribution of polychromatic light. When mixing polychromatic light, lights having only one wavelength are successively fed to each member of a selective chain to form a partial spectrum, and when distributing chromatic light, one wavelength is filtered out of each member and the remaining spectrum is fed after reflection to the next member for being further decomposed. A chain of photonic crystals is used both for mixing and distributing and a wavelength-selective coupler/decoupler is associated to each crystal. Fields of application include the wavelength-selective mixture or distribution of polychromatic light and spectrometric measurements and environment monitoring.
