Abstract :
A highly compact Mach-Zehnder (MZ) electro-optic (EO) modulator composed of nanoscale metal gap waveguides has been numerically demonstrated. Nanoscale propagations and their EO modulations are investigated by the FDTD method considering the Lorentz-Drude model. The half-wave voltage (Vπ) of the resulting MZ modulator is 1.73 V using the interference arm with a sub-micron length (500 nm).
