Description

[Brief explanation of drawings]

1 and 2 respectively show a part A of an optical communication device, a light emitting device B, and a communication optical fiber C to be connected to these, L is light or a light ray, and FIG. 3 shows a connecting optical fiber according to the present invention. The figure on the right is a side view of this, particularly showing how light enters from the left, meandering mainly within the core, and heading towards the narrow right end 3. Figures 4 and 6 show large and small versions of the fiber of the present invention.
The figure shows the case where the large diameter end face of the proposed fiber is made into a spherical concave surface, Figure 7 shows the case where the large diameter end of the proposed fiber is made square or rectangular, and Figure 8 shows the S-S line of the apparatus shown in Figure 1 before light leakage. When the fibers of the present invention are fused and the fibers of FIG. 9 and 10 are used for receiving light from the emitter of FIG. 2 and the fiber of FIG. 4 is used for receiving light from the light emitter of FIG. shows the use of the fiber of the present invention due to its high light yield when the rod lens 13 is used in reverse.

Claims (1)

[Scope of utility model registration request] It is a tapered optical fiber consisting of a cladding and a core, with one end having a large diameter that receives the emitted light from an optical communication device, and the other end having an outer diameter and a core diameter equivalent to that of a thin optical fiber for communication. It is characterized by the rate distribution increasing rapidly from the surface towards the inside, then gradually increasing from there to the core, then entering the core where it increases rapidly even more than the previous time, and then increasing even higher in a mountain-like manner to the center of the core. Optical fiber for connection shown in the name of the invention.
