A method for tuning fiber optic coupler and wavelength division multiplexer devices comprises the steps of fusing optical fibers having a refractive index responsive to ultraviolet radiation to form a coupling region having a coupling ratio dependent upon the refractive index, and subjecting the coupling region to ultraviolet radiation to adjust the coupling ratio to a pre-determined value at a given operating wave length.
