AN ELECTROOPTIC SWITCHING STRUCTURE ON III-V SEMICONDUCTORS USING THECOHERENT COUPLING OF RADIATION MODES

In this paper we propose a new structure for electrooptic switching us ing the coherent coupling of radiation modes. The proposed structure i s studied using both the non-modal Beam Propagation Method (BPM) and a modal technique based on the analysis of the radiation mode spectrum generated at each optical discontinuity in the structure. The analysis shows that the proposed structure may have a distinction ratio of 12 dB with radiation losses in the order of 3.5 dB in the ON state.
