First Claim
1. A method of optimizing the use of a base material in manufacturing optoelectronic components with variable-period grating, the optoelectronic components having edges corresponding to an x direction and a y direction, the method comprising the steps of:
- choosing at least one individual component pattern, obtaining a first geometric variant of the at least one individual component pattern by performing a 180 degree rotation around an axis that is perpendicular to a surface of the individual component pattern and obtaining a second geometric variant of the at least one individual component pattern by mirroring; and
creating a unit cell for forming a waveguide on the base material, the unit cell being formed from at least one of the first geometric variant, the second geometric variant and the at least one individual component pattern, the continuity and differentiability of the waveguide to be formed by the unit cell being ensured.

Abstract
Disclosed is a method for the optimum utilization of disk-shaped base material in the manufacture of optoelectronic components with variable-period grating. The method helps avoid material losses by arranging optoelectronic components on a disk-shaped base material in an optimum manner and is based on obtaining variants of nominally identical individual component patterns by mathematical rotation and mirroring, forming a unit cell through shifting of the individual component pattern variants, and reproducing the unit cell in the x and y directions until the active surface of the mask or the entire surface of the disk-shaped base material is tightly covered. The method may be used for the manufacture of photonic components based on DFB, DBR, or sampled grating structures.
