ABSTRACT:
A fused optical fiber coupler comprising a first pair of axially elongated cylindrical fibers, each having a circular transverse cross-section of a first diameter, the first pair of fibers being in fused contact with each other along a continuous line and forming grooves on opposite sides of the line. A second pair of axially elongated cylindrical fibers each having a circular transverse cross-section of a second diameter different than the first diameter of the first pair of fibers, one fiber from the second pair of fibers being disposed in each of the grooves and fused to each of the first pair of fibers.
