Abstract
A telecommunication system having frequency-dividing optical components where light pulses having different frequencies are coupled out of a optical fiber by fiber grating and/or photonic crystals and imaged by focusing elements outside of the optical fiber. The fiber grating for different frequencies can be used in a single period or in different periods disposed one after the other. The photonic crystals can be used at the optical fiber extremity or etched in a channel or trench in a glass fiber. Delay elements are added to ensure that different frequency light pulses are imaged simultaneously in a given and desired time relation as required for further parallel processing.
