Abstract

A method of high-density optical disk structure design using computational electromagnetic FDTD analysis is proposed. A staircase method is used to simulate the realistic sidewall geometrical structure of the land-groove of phase-change optical disk. The phase-change materials appear as different optical characteristics under irradiation of different frequency laser beam. Materials models in the FDTD scheme have been studied to solve the computational instability. Using this FDTD method, the structures of the phase-change optical disk with blue laser and high-NA system are investigated.
