METHOD FOR OPTIMIZED UTILIZATION OF BASE MATERIAL IN THE MANUFACTURE OF OPTOELECTRONIC COMPONENTS WITH VARIABLE-PERIOD GRATINGS

摘要

] 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.
