Abstract

A modification of the Beam PropagationMethod (BFM) is suggested so that only one integral has to be evaluated instead of two for every two iteration. This will reduce computational time as well as errors. Also for a medium whose refractive index does not vary along propagation direction we have suggested a matrix method which takes very less computer time as agaiflst the conventional BPM. The method is applied to the combinar tion of microlens and taper. I
