Abstract

PURPOSE: To make themanufacture of the photo distributor and enhance reliability by using the transparent body having the refractive index distribution producing the action equivalent to the curved faces of the photo distributor comprising combining a one-dimensional focusing type optical transmission body and curvend faces in place of said curved faces.
CONSTITUTION: An incident optical fiber 21 is connected to the incident face 11 of a one-dimensional focusing-type optical transmission body 1 having the refractive index distribution decreases in proportion approximately to the square of the distance from the center toward the periphery only in the Y direction and a transparent body 3 having the refractive indixes reducing in proportion approximately to the distances from the faces 42 thru 45 parallel to the y z faces only in the x direction near said faces is bonded and secured to the exit end face 12. A one-dimensional focusing type optical transmission body 2 having the similar refractive index distribution to that of the optical transmission body 1 is bonded and fixed to said transparent body 3, and exit optical fibers 22 thru 25 are connected to its exit end face 14. The end faces of the respective optical elements can be plane in this way and since these are mutually bonded and fixed, the manufacture is easy and the reliability of the photo distributor may be enhanced.
