Optical telecommunication interconnections high contrast refraction index optical guide having central section surrounded outer sections lower refractive index and intermediate layer having refractive index between center/outer layers |
摘要 |
The optical guide has a center (12) with side sections. There are first and second holding layers (14,16) outside the center having lower refractive indices than the center. There is an intermediate layer (18) between the two outer layers and round the center with a refractive index above the central refractive index and lower than the outer refractive index.
