Abstract :
The finite-element formulation using the vector magnetic field and a penalty function to eliminate spurious modes was used for the analysis of unusual arrangements employing rectangular-core directional couplers with refractive indices chosen to match the characteristics of organic materials. The structure proposed is a fast electro-optic modulator/sensor that could be made by employing the electro-optic organic material 2-methyl-4-nitroaniline (MNA) without the need for special crystal growth methods. To verify the validity of the finite-element analysis, results for a coupling arrangement using materials of index close to 1.51 were compared with data from experimental measurements
