APPROXIMATE CALCULATIONS OF DISPERSION CHARACTERISTICS OF TE MODES IN NONLINEAR SYMMETRIC SLAB OPTICAL WAVEGUIDES
非线性对称平板光波导TE模色散特性的近似计算

A perturbation method has been developed to derive the approximate computing formulae of propagation constants for TE modes on Kerr-type nonlinear symmetric slab optical waveguides. It has been shown that the results obtained from the present formulae agree very well with the exact ones.
