Resonators having resonating elements (18,19,28,29) are arranged such that they laterally surround respective planar optical waveguides (13,23). Deflectors (16,26) couple radiations propagating through waveguides with common radiation modes (30), defined by adjustable geometrical and material properties of coupler, to obtain wavelength selective coupling of radiation, when resonators are tuned to same resonance wavelength. - Independent claims are also included for the following: - (1) an array of optical couplers; - (2) a method for fabricating the optical coupler; and - (3) use of optical coupler. |
