Abstract
Results of the Discrete Layer Peeling (DLP) inverse scattering algorithm do not directly correspond to Bragg grating's technological parameters. We propose a method of transforming a stack of discrete complex reflectors resulting from DLP into physical and geometrical parameters of a Bragg grating suitable for fabrication in planar technology. Particularly, the method keeps lengths of grating sections (teeth and grooves) above a required technological minimum. While the stack of complex reflectors is a natural output DLP, it can also be computed from a space distribution of the complex coupling coefficient determined in other ways.
