Optical gratings that perform a number of functions at various wavelengths are formed by various methods that preserve spectral information within a wavelength band, the functions including: coupling radiation from one waveguide to another, controllable gratings that operate on different wavelengths in response to external control signals.

Des réseaux optiques qui réalisent un certains nombre de fonctions à diverses longueurs d'onde sont formés par divers procédés qui préservent des informations spectrales dans une bande de longueur d'onde. Ces fonctions comprennent: le couplage de rayonnement d'un guide d'onde à un autre, des réseaux commandables qui fonctionnent sur différentes longueurs d'ondes en réponse à des signaux de commande externes.
