Electro-optic tuning in ferroelectric capacitor with photonic crystal nanobeam cavity

In conclusion, an ultracompact, energy efficient PCNBC based electric-optic tuning with an Au/P(VDF-TrFE)/Si ferroelectric capacitor is proposed and realized. The device demonstrates supreme properties such as a small footprint and low energy consumption. The ferroelectric poling of P(VDF-TrFE) is confirmed by measured P-V hysteresis loop, while the ferroelectric based electrostatic doping effect is reflected in our on-chip electro-optic measurements. By introducing the hysteresis properties and memory applications of ferroelectrics to silicon photonic platforms, it opens a new path for the development of on-chip optoelectronic integration.
