Title:
【発明の名称】多モードファイバ中への光の効率的な結合および改善されたパワー処理のための前端部処理方法
Document Type and Number:
Japanese Patent JP3131198
Kind Code:
B2
Abstract:
A method of front end preparation for efficient coupling of light into a fiber (10) while preventing fiber damage from an incident beam, includes the steps of stripping an end of an outer cladding (12) of the fiber (10). The step of stripping produces a stripped end (19) of the fiber (10). The stripped end (19) is then coated with a polymer (17) to produce a polymer coating (14) such that a length of a core (11) of a multi-mode fiber (or an inner cladding of a single-mode double cladding fiber) is bare beyond the polymer coating (14). Thereby, an extended end (13) of the core (11) or inner cladding (11) is left. For a portion of an incident beam that misses the core (11) or inner cladding (11), such portion is allowed to diffract from the extended end (13), while leaving the fiber (10) undamaged.
