Nonconservation of power is a perplexing problemin the propagating beam analysis of transverse magnetic (TM)waves in a -variant step-index optical waveguide. To conservethe power in terms of a squared norm, a modified finite-difference(FD) formula is introduced that allows a general positionof a core-cladding interface. The use of the modified formulacontributes to a reduction in a field profile error caused by astaircase approximation with subsequent conservation of power,particularly for a symmetrical waveguide. To obtain the powerconservation even in the analysis of an asymmetrical waveguide,a -derivative of the refractive index is taken into account. Anasymmetrical taper and tilted waveguides placed in parallel areinvestigated to validate the present technique.
