Paper Abstract

Here we proposed three adiabatically coupled waveguides (ACW), while the outer waveguides perform as a two-mode system analogous to ground- and excited- states and the middle waveguide is same as dark-state in a three-level-atomic system. Thanks to the dark-state, intermediate waveguide is based on plasmonic Indium thin oxide (ITO) as an active structure. Our simulation indicates a power consumption of 40 atto-joule with 50 dB modulation depth. In addition, our ACW plasmonic modulator provides high-speed operation as high as 5.4 THz and insertion loss as low as 0.45 dB. The proposed device is crucial for futuristic of optical short-reach interconnects.
