| Abstract: | The mode theory of the A - axis single crystal fiber (SCF) , the dispersion relation of the A - axis SCF and the configuration of transverse electrical field are thoroughly presented, and the change of dispersion relation with the core anisotropy deo and the cladding anisotropy deod analyzed. The exact expressions of transverse field are found by solving the electromagnetic equations of strongly anisotropic A - axis SCF. With the boundary conditions to the first order, the dispersion equations of strongly anisotropic A - axis SCF are obtained. The dispersion curve and the configuration of the transverse electrical field are also discussed by numerical calculation. |
