OPTICAL FIBER COLLIMATOR SYSTEM, OPTICAL FIBER COLLIMATOR ARRAY, PRODUCTION METHODS FOR OPTICAL FIBER COLLIMATOR SYSTEM AND OPTICAL FIBER COLLIMATOR ARRAY

摘要

The type to form welding in the grin lens by optical fiber one end that a kind of GRIN optical fiber fuses is contained at least one selected from Sb2O3, Ta2O5, TiO2 or ZrO2 by quartz glass. Due to there is no adhesive material for when engaging GRIN optical fiber lens pair, optical characteristics will not to deteriorate, with GRIN optical fiber lens can easily with the effect due to setting welding certainly. When the grin lens of index distribution constant (g) are in appropriate range, coupling loss can be greatly reduced.
