Title:
OPTICAL FIBER COUPLING COMPONENT AND PROCESS FOR PRODUCING THE SAME
Document Type and Number:
WIPO Patent Application WO/2006/082625
Kind Code:
A1
Abstract:
An optical fiber coupling component that reduces the difficulty of core alignment
operation, lowers any coupling loss and is free from deterioration of optical
performance. An optical fiber is fusion spliced to an end of GRIN lens of quartz
glass containing as a refractive index regulating substance at least one member
selected from among Sb2O3, Ta2O5,
TiO2 and ZrO2. Any deterioration of optical performance
can be avoided as no adhesive is used, and the core alignment between the GRIN lens
and the optical fiber can be facilitated by self alignment effects. Further,
the coupling loss can be strikingly reduced by causing the refractive index distribution
constant (g) of GRIN lens to fall within an appropriate range.
