Abstract:
D-shaped POFs are used to form a 2-to-1 optical coupler. The D-shaped POFs are produced via an extrusion process that is relatively inexpensive to perform and that can be performed with relatively high manufacturing throughput. The D-shaped POFs are bonded together to form a coupler end face having a generally circular cross-sectional area. The coupler end face is interfaced with an end face of a main POF that is generally circular in cross-sectional shape. The resulting D-shaped 2-to-1 optical POF couplers have relatively low insertion loss and relatively high optical coupling efficiency.
