The paper studies non-iterative bidirectional beam propagation method based on scattering operators which is used in numerical analysis of optical waveguide with abrupt longitudinalrefractiveindex.
Then the simplified model for the LPFG is deduced with ignoring longitudinal coupling of modes and coupling of cladding modes themselves, and also assuming the modulation of refractiveindex exis...
