Strained silicon was proposed more than a decade ago promising to revolutionize the photonics field by allowing efficient modulation in this platform. Despite all efforts, still rather low χ(2) values have been measured strained devices. In addition, way of applying strain has not barely changed since concept proposed, usually consisting on waveguide covered stressor material such as nitride. l...

Precise measurements of electrostatic fields in harsh environments are required ranging from particle accelerators to industrial installations. Many techniques disrupt the field distribution due presence conductors. We present a fully dielectric sensor for very environmental conditions, that exploits Pockels effect manifested by electro-optic crystals. This system is designed allow DC be perfor...

Ferroelectric materials offer unprecedented ultrafast responses and are of great interest for the development new polarizable media under influence an electromagnetic field. Recent research efforts have demonstrated role optical excitation intense terahertz (THz) pulses in inducing a polar order revealing hidden phase transition SrTiO3 (STO), respectively. Here we show that surface STO crystals...
