A method for monitoring light propagation through a guiding structure, the method comprising:

• optically coupling a resonator structure to said guiding structure and optically coupling a detector to said resonator structure, to thereby extract a portion of light propagating in the guiding structure and the transfer it to the detector;
• providing the coupling between the guiding structure and the resonator structure smaller than coupling between the resonator structure and the detector.

Thc method according to clam 28, comprising analyzing the detected portion of the multi-channel light to identify characteristics of individual channels in the multi-channels transmissions through the guiding structure.
