Application of discrete layer peeling algorithm for design of selective photonic devices obeying the constraints of the fabrication process

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.
