ABSTRACT:
The present invention relates to an input/output fiber coupling device for an optical fiber. The device includes a chamber wall having an opening at one side and a bore at the opposite side. The chamber wall forms a cavity therein. A focusing lens fits within the opening, the lens having input and output laser beam paths aligned with the fiber longitudinal axis, and focuses a laser beam onto the end face of the fiber which is inserted into the cavity through the bore. An index-matching fluid circulates within the cavity between the lens and the fiber end face.
