In addition, the present invention also provides a kind of method for making of double-layer fiber array, and its step is following:

A, ground floor optical fiber is inserted in the V-shaped groove of V frid, and apply at two ends 190-210g pulling force, make it to be fitted in the V groove, direction of pull is along deflection 25-35 ° straight down of shaft axis of optic fibre.

B, second layer optical fiber is placed in the formed groove of adjacent fiber of ground floor optical fiber, and apply the pulling force of 90-110g at two ends, direction of pull is consistent with ground floor optical fiber direction of pull;

The shaft axis of optic fibre direction of C, horizontal adjustment second layer optical fiber, the angle tilt that makes second layer optical fiber and ground floor optical fiber is less than 5 degree;

D, adjust after, the pulling force of second layer optical fiber is increased to 190-210g;

E, above second layer optical fiber, place a glass plate and on glass plate, apply the pressure straight down of 90-110g;

F, point solidifies glue on optical fiber, makes glue penetrate between V-shaped groove and the glass plate fully and waits to solidify the glue full solidification;

The end face of G, the double-layer fiber array after will solidifying grinds, polishing.

Adopt technique scheme, double-layer fiber array of the present invention has the closeness height, and precision is good, advantages of small volume, the advantage of low production cost.
