Abstract
This paper describes the behavior of optical diffraction gratings which have been weighted in various ways analogous to those used in surface acoustic wave devices. It is shown experimentally and theoretically that a wide variety of 2-D responses can be achieved by these means. In this study we have chosen to concentrate on quasirectangular responses, and we describe the factors that limit the performance achievable in practice. Some possible applications of these techniques in the spatial, temporal, and spectral domains are mentioned.
