Patent ID: 6922505

Claim:
A method, comprising: fixedly supporting on a support section a further section which is operable to transport radiation containing a plurality of signal components at respective different frequencies along a path of travel; fixedly supporting a dispersive section on said support section so that said signal components pass therethrough, said dispersive section having a dispersive characteristic that deviates a direction of travel of each said signal component by a respective different amount so as to effect an optical mapping for each said signal component between said path of travel associated with said further section and a respective further path of travel; providing a plurality of optical fibers which each correspond to a respective said signal component; positioning an end of each said optical fiber in the region of a respective said further path of travel; for each said optical fiber, causing a beam of radiation which includes the corresponding signal component to travel along one of a path of travel through that optical fiber and said path of travel associated with said further section, and to then be optically mapped by said dispersive section to the other thereof; and adjusting a position of the end of each said fiber while monitoring the amount of the corresponding signal component traveling along the other of said paths of travel, until the end of that fiber is disposed in a selected position, and then fixing the end of that fiber in said selected position thereof with respect to said support section.
