| 英文摘要 | It is known to couple a collimated beam of light into the end of an optical fiber with a graded index lens having an angled facet at the lens/fiber interface to reduce the amplitude of Fresnel retro-reflected power. The expense incurred in providing angled facets is avoided by using a two-part compound lens. One part is a graded index lens part having an axial length shorter than a quarter period. To this is bonded a cylindrical uniform refractive index lens part whose index is matched with the effective refractive index of the fiber. This reduces the amplitude of the retro-reflection power by causing the displacement of the Fresnel reflection from the lens focus. |
