Abstract
A fiber optic coupler (15) is constructed by inserting optical fibers (11, 12) into a glass tube (23). Glass frit is placed in the glass tube (23) to fill-in the space between the optical fibers (11, 12) and the glass tube (21). The tube (23) is heated at a center portion (21), which fuses the glass frit and thereby strengthens the fiber optic coupler (15) at its critical cross-section. The coupler has high efficiency and structural stability, both of which are advantageous when used with fiber optic gyroscopes.
