Figure 4 is a light intensity distribution diagram at the end face of the side-opening lens. Figure 4 is a ray trajectory diagram when a conventional optical splitter is used as an optical coupler. Figures 5 and 6 are optical layout diagrams of the optical splitter and coupler based on this invention. Figure 7 shows the output side of the optical splitter and coupler according to this invention when used as an optical splitter and when used as an optical coupler. This is a light intensity distribution diagram of the end face of a rod lens. In the figure, 1a to 1c are optical fibers, 2a to 2c are rod lenses, 3 is a right angle mirror, and 4 is the center line of the end surface of the rod lens. It should be noted that the same or corresponding parts in the figures are indicated by the same reference numerals.

徴とする光分岐結合器。The light emitted from the first optical fiber is converted into a parallel beam by a first rod lens, divided into two by a right-angle mirror, and condensed by second and third rod lenses to be transmitted to the second and third optical fibers. The function of the optical splitter is to convert the light emitted from the second and third optical fibers into parallel beams by the second and third rod lenses, and to create a 90° optical path on the slope of the right angle lens. In the optical branching/coupling device having the function of an optical coupler in which light is condensed by the first rod lens and coupled to the first optical fiber, the optical axes of the second and third rod lenses intersect each other. An optical branching coupler characterized in that the ridge line of the right angle mirror is arranged so as to protrude from the line by about 10 to 20% of the diameter of the lens.
