Calculation of the diffraction field in a layered medium illuminated through a phase mask

Аннотация

A local mode technique has been developed for calculating a diffraction field in a layered medium illuminated by the TE-polarized light through a phase mask with a surface-relief diffraction grating. This technique has been used to evaluate the possibilities for optimizing conditions of the formation of refractive index Bragg gratings with the use of ultraviolet standing waves in polymer waveguides on a silicon substrate.
