Title: Photocoupler
Inventor: NAKAGUCHI TOMOYUKI
IPC: G02B6/28
Filed: 1983-05-02
Abstract: PURPOSE:To attain coupling with small loss by bundling output terminals of plural optical fibers for transmission, and connecting an optical fiber for reception which has a large diameter thereto. CONSTITUTION:When the core part of the optical fiber 2 for reception is large enough to include 32% of each core part of optical fibers 1a and 1b for transmission in an output end surface of the optical fiber bundle, light signals from the fibers 1a and 1b are multiplexed and coupled with the fiber 2 with an about 5dB coupling loss. Therefore, the coupling loss is improved the more when the core part of the fiber 2 has a size the larger than the size including 32% of the core part, and when the core part includes the core part by 100%, the signal signals from the fibers 1a and 1b are multiplexed and coupled with the figure 2 with only an aoubt 0.3dB Fresnel loss. Neither a rod lens nor a half-mirror is used, so the cost is reduced.
