Claim 15:
16. The method of claim 14, wherein the optical coupling step implements an active alignment device, the active alignment device comprising a first alignment input, a first alignment output a second alignment input and a second alignment output selected from, respectively, the at least one first input, the at least one first output, the at least one second input and the at least one second output, wherein the first alignment output and the second alignment input are optically coupled and define in that order a first alignment path, wherein the second alignment output and the first alignment input are optically coupled and define in that order a second alignment path, and wherein the optical coupling step comprises emitting light radiation that when it travels along one of the first alignment path or the second alignment path then travels along the other of the first alignment path or the second alignment path.
