Abstract :
A metal-clad directional coupler-based polarizer with two-dimensional (2-D) modal confinement has been designed and its performance has been rigorously computed by using the accurate vector H-field finite element method after taking into consideration the polarization-dependent coupling lengths, phase mismatchings and losses due to metal-cladding of the system involved
