Why Use RSoft ModePROP EME
RSoft ModePROP uses the eigenmode expansion (EME) method to efficiently model light propagation in waveguides, couplers, tapers, mode converters, and photonic integrated circuits. By accounting for forward- and backward-propagating optical modes as well as radiation modes, engineers can accurately analyze coupling efficiency, propagation behavior, and device performance before fabrication.
