Abstract

A simple method is proposed for studying the spectral response of a first-order waveguide grating filter with random fluctuations in the period of the grating. The method can be applied to any grating groove shape, and it can be used to study the effect of both random and systematic variations in other grating filter parameters The numerical calculations using this model are simple to carry out, but may be time-consuming in some cases. Results are presented for grating filters with rectangular and triangular grooves.
