TL;DR: A dramatically increased EO beam deflection in relaxor ferroelectric potassium tantalate niobate (KTN) crystals is reported by using the electric-field-enhanced permittivity to offer a wider deflection range and a lower driving voltage.

TL;DR: In this paper, the electric field-induced phase transition in perovskite relaxor ferroelectric crystals has been studied using Raman spectroscopy, and it was shown that the intensity of the Raman spectrum of electric field induced phase transition is a function of temperature and thermal history.

TL;DR: Anomalous electro-optic potassium tantalate niobate (KTN) devices are reported, in which both electrons and holes were injected into the KTN crystal via ultraviolet (UV) illumination-assisted charge injection, to enable the new bi-directional scanning capability.

TL;DR: An ultralong lock-on time on the order of millisecond is achieved, which is 3 orders of magnitude longer than a typical lock- on time of high-gain GaAs PCSS, consisting of a semi-insulating gallium arsenic (GaAs) substrate and a front-bonded ruby crystal.

TL;DR: In this article, an ultrahigh light extraction efficiency (LEE) light emitting diodes (LEDs) by incorporating innovative asymmetric obtuse angle microstructured surfaces was reported.
