Abstract :
We report on the design of small multilevel diffractive elements. The specific design problems that arise due to the limited size are discussed and it is shown that direct search and simulated annealing are appropriate tools to find a good solution. However, good convergence is only guaranteed if the algorithms are properly initialised
