Abstract

The rigorous coupled-wave analysis and our experimental measurements show optimal values of the phase retardation and duty cycle of the phase mask to minimize zero and even diffracted orders, that are more precise than that usually used according to the scalar theory of diffraction. Under an oblique incidence, we optimize the phase mask with three parameters: phase retardation, duty cycle, and refractive index, that results in a perfect sinusoidal interference field with high diffraction efficiency for writing the fiber Bragg grating.
