ABSTRACT:
An improved wavelength division multiplexing (WDM) coupler includes a dual fiber collimator assembly (27), a filter device (29), and a single fiber collimator assembly (31). The filter device comprises a holder (26) and a filter (24) received therein. The holder has a first opening (21) and a second opening (23) communicating therewith. The holder firmly secures both the dual fiber collimator assembly and the single fiber collimator assembly therein. A relative position and orientation of a first GRIN lens (22) and the filter can be adjusted during assembly by sliding the first GRIN lens in or out of and by microtilting the GRIN lens in the second opening while monitoring reflection insertion loss. A DWM coupler which is more easily adjusted during assembly and which has a more stable structure is thus obtained.
