Perfectly coupled

Making single-mode fiber coupling smooth and permanent
by Christian Knothe, Anja Knigge and Ulrich Oechsner

Long-term stable fiber-coupling requires sub-micron precision and pointing stability. This is especially true when a polarization-maintaining single mode fiber is to be permanently attached to a free beam laser. Tests of a popular single-mode coupler have shown that it is possible to achieve outstanding longterm stability over a wide temperature range while having a sensitive adjustment procedure. [more]
