| 摘要 |
The present invention comprises a coupling device for the transmission of light information between fibre-optic elements. This device comprises a first fibre-optic transmission element 50, a second fibre-optic transmission element 60, each fibre-optic transmission element comprising a core 50b, 60b of relatively high refractive index and a cladding 50a, 60a of relatively low refractive index and a means 52 for the transmission of light information from this first element to this second element. The invention can be used, for example, in the communication field. <IMAGE>
