Abstract
A coupler for coupling light between an optoelectronic element and an optical fiber. The coupler has a fiber stop that is made of a material that has an index of refraction that effectively matches the index of refraction of the optical fiber being coupled to the optoelectronic element. The fiber stop may be flat or rounded. It may be a discrete or molded part of the coupler assembly. The end of the fiber being stopped may be flat or rounded.
