The mode field and the translational efficiency are studied by the finite difference beam propagation method in an anamorphic photonic crystal fiber. Selective hole collapse is realized in laboratory and anamorphic fibers with circular to rectangular cores and small to large mode fields are made. The loss at wavelength 1550 nm is below 0.05 dB during each translation. The calculated and the experimental results are consistent with each other.
