Hybrid plasmonic electro-optical modulator

AbstractA high-performance CMOS compatible electro-optical modulator (EOM) is proposed, simulated and analyzed. The EOM is based on an asymmetric hybrid plasmonic waveguide on a silicon-on-insulator platform. Using the finite difference time domain simulation method, we obtained the transmission spectrum of the modulator. An insertion loss of 0.25 dB is achieved for a 5-μm-short modulator. The extinction ratio is optimized to be as high as 30 dB at a wavelength of 1.55 μm. Broadband operation of 600 nm is feasible since no resonator is deployed .
