Abstract
A perturbation and iterative perturbation analysis of linearly chirped quasi-periodic structures of mediumQfactor in planar dielectric waveguides has been formulated. This analysis can be used to calculate the diffraction efficiency and the angular field of view of a given linearly chirped grating structure, for a specific incident beam including the effect of higher orders of diffractions. The numerical example of aF = 10 , f = 10m.m,\Lambda_{\min} = 2.06, \Lambda_{\max} = 4.25and grating groove length = 15 μm is presented.Keywords
