High Transmission Efficiency of Opto-electronic Devices Using Active Hybrid Plasmonic Coupler

This paper discusses modeling and optimizing the performance of hybrid plasmonic bidirectional coupler which is used as a basic building block in modeling high transmission efficiency of opto-electronic devices such as filter, wavelength division multiplexer, logic gates, and switching matrix with the help of an active material (indium tin oxide) that has an electrically adjustable permittivity. All the proposed devices satisfied high transmission efficiencies at the desired output ports over a suitable wavelength range. The realized structures are characterized and simulated by 3D finite-difference time-domain (FDTD). The components would be useful in the optical interconnection networks, photonic integrated circuits, and signal processing system.
