The rotator type of optical modulating component modulator requires a planar angular rotator to control different angles for modulating the dissimilar light. If simply using the S-shape beam to behave a pin-joint, the rotator angle will be limited. The design target accordingly needs to maximize the range of output angle for satisfying the prescribed linear output positions or can be a sort of the generation function between the input and output. This paper applies the material distribution method of SIMP (Solid Isotropic Microstructure with Penalization) in the topological optimization to deal it. The objective function consists of maximizing the output range and minimizing the error between prescribed function and real output function with volume limit as the design constraint. The model presented in this paper is a preliminary successful work that requires further efforts towards the practical phase.
