ABSTRACT:
A WDM coupler includes a first collimator including a single fiber pigtail, a first GRIN lens and a first glass holding tube; a second collimator including a dual fiber pigtail, a second GRIN lens and a second glass holding tube; an optical filter arranged on an end surface of the second GRIN lens of the second collimator; an outer glass sleeve bridging the first and second collimators; and UV-curing epoxy between the outer glass sleeve and the glass holding tubes of the first and second collimators for securing the first and second collimators to the outer glass sleeve. The expansion coefficient of the UV-curing epoxy is matched to that of the glass materials of the outer glass sleeve and the first and second holding tubes, so that the first and second collimators can directly be fixed in the outer glass sleeve using the UV-curing epoxy.
