CRYSTALWAVE and OMNISIM are modeling tools from Photon Design which are offered as a software bundle from CMC.
CRYSTALWAVE is a design environment for the layout and design of integrated optics components. It supports Finite-Difference Time-Domain (FDTD), Finite Element Frequency Domain (FEFD) and Finite Element Time Domain (FETD) simulators and includes a mask file generator specifically optimized for planar photonic crystal structures.
OMNISIM is a design environment for the omni-directional layout and design of integrated optics components. It likewise supports FDTD, FEFD and FETD simulators.
