INTEGRATED OPTICS

A new change of phase

Ferroelectric domain switching controlled by electrical pulses provides a controllable means to tune the refractive index of BaTiO3 thin films. Now, a device based on this material is presented that is capable of implementing low-power, high-speed and CMOS-compatible programmable phase shifters in silicon photonic chips.
