Multiphase CGH design of reconfigurable chip or board-level optical interconnection

The method for the multi-phase computer-generated-holography (CGH) design of reconfigurable chip or board level optical interconnection is discussed in this paper. First, an improved direct search (DS) algorithm for the multi-phase CGH design is presented. Using this method, the high quality multi-phase CGH can be calculated very quickly, and the computation complexity is much lower than the other algorithms such as the most popularly used DS method and SA method. Then, how to use this algorithm for the CGH design of the reconfigurable chip or board level optical interconnection is given.
