Claims
- 1. A process for the preparation of an optical coupler, which comprises arranging a light branching-coupling optical fiber defining an axis in an optical fiber-inserting hole of a block having an abutting plane, the abutting plane of the block having an angle .theta. of 360.degree./N (where N stands for an integer of not less than 2) to the fiber axis, so that a distal end of the optical fiber projects slightly from the optical fiber-inserting hole at said abutting plane, heat-treating the projecting portion of the optical fiber by a heating apparatus having a heating plate engageable with the abutting plane of the block to cause a plastic deformation of the projecting portion of the optical fiber inserted in the block thereby forming a light-coupling plane at the distal end of the optical fiber coincident with the abutting plane of the block, thus fixing the optical fiber in the block to construct a light branching-coupling part.
- 2. A process for the preparation of an optical coupler according to claim 1, wherein the angle .theta. is 3 to 30.degree..
