  The equatorial current sheets outside the light cylinder(LC) are thought as
the promising site of the high energy emission based on the results of the
recent numerical simulations. We explore the pulsar light curves and energy
spectra by computing the curvature radiation based on the FIDO magnetospheres.
The FIDO magnetospheres with a near force-free regime inside the LC and a
finite but high conductivity outside the LC are constructed by a spectral
algorithm. The pulsar high energy emission properties are explored by
integrating the trajectories of the test particles under the influence of both
the accelerating electric field and the curvature radiation losses. As an
application, we compare the predicted energy-dependent light curves and energy
spectra with those of the Crab and Vela pulsars published in Fermi 2PC catalog.
We find that the observed characteristics of the light curves and energy
spectra from Crab and Vela pulsars can be well reproduced by the FIDO model.
