Abstract
A versatile technique is demonstrated to fill selectively a fluid into
desired air holes in a microstructured optical fibers (MOFs). A fan-shaped
groove is carved on the fiber surface to expose selected air holes to
atmosphere by a micromachining system consisting of a femtosecond IR laser
and a microscope. Then a fluid is filled into the exposed air holes through
the carved groove with the well-known capillarity action. Such a technique
can be used to fill selectively several different types of fluid samples
into desired air holes in an MOF by means of carving fan-shaped grooves on
different orientations of the fiber surface.
