横向偏差为±1.0 μm

沿着

X-Y

角向偏差最大

横向偏差次之

轴向偏差最小。

Abstract

The coupling efficiencies of the ball lenses used in coupling of the laser diode(LD) and single mode fiber(SMF) were calculated and researched by a energy integration method. Research results indicate that when the single ball lens is used in the LD-ball lens-SMF system

the axial alignment tolerance is ±30 μm

the lateral alignment tolerance is ±1.0 μm and the tilting on the

X-Y

plane pivoting at the fiber tip is ±1.2°. When the double ball lenses are used in the LD-ball lenses-SMF system

the coupling loss of the tilting tolerance is maximum

the coupling loss of the lateral alignment tolerance is smaller than that of the tilting tolerance and the coupling loss of the axial alignment tolerance is minimum.
