3-DIMENSIONAL FULL-VECTOR ANALYSIS OF OPTICAL WAVE-GUIDES BY FINITE-INTEGRATION BEAM-PROPAGATION METHOD (FIBPM)

In the paper a novel finite-integration beam-propagation method (FIBPM ) is presented. This method is especially suited for the simulation of optical waveguides containing extremely thin layers of complex permit tivity. For calculating the propagating optical field an efficient alg orithm based on expansion of the matrix exponential in Chebyshev polyn omials is applied. The derivation of the propagation algorithm is give n, also detailing the convergence criteria. A code for a massively par allel computer has been developed and applied successfully to complex waveguide structures used for high-power laser diodes.
