Abstract

In this paper a software package for design of bulk wave acousto-optical (AO) spatial light deflectors is reported. This package consists of a main program and the following modules: a database of acousto-optic materials, a program for coordinate transformation, a multi-layer transducer analysis program with the capability of matching layer, and matching circuit design, an acousto-optic interaction analysis program, and a user friendly interface. The heart of the package is the acousto-optic interaction program based on rigorous coupled wave analysis in anisotropic media. The polarization of input optical beam can be TE, TM, or mixed. The beam can have either uniform or Gaussian intensity profile. The user chooses the bandwidth, central frequency, the laser wavelength and polarization, the preferred AO material, and then the program provides all the geometrical parameters of design and plots the results of its simulation. The program accepts constraints on spatial resolution and transit time, as well. Several examples, both single and multi-frequency problems have been done using this package. An example comparing a result of this package with a previously reported one will be addressed in this paper. At present this package is restricted to single element transducer designs.
