Photonic crystals have been widely studied in the fields of physics, material science and optical information technology. In general, the standard rectangular FDTD method is used to predict the performances of photonic crystals even if it is very time consuming and inefficient for the structures with non-orthogonal structures or inhomogeneous media. The current authors developed a software called GCFE, which is based on non-orthogonal FDTD method .The upgraded version of GCFE software can be used to calculate the photonic band structures, states density, transmission and reflection coefficients of one dimensional to three dimensional photonic crystals. It has the characteristic of efficient calculation and simple manipulation. In the present paper, the system structure of GCFE software is presented and the implementation of the algorithm module and the result display module are described in detail. Finally the band structures, transmission and reflection coefficients and photonic states density for the photonic crystal fibers with cube structures are calculated by our GCFE software and the numerical application results are also shown and discussed.
