Abstract

We report on several recently demonstrated microphotonic devices based in ferroelectric single crystals. The device concept is to micro-pattern ferroelectric domains in the shape of lenses and prisms whose refractive index is electric field tunable through the electro-optic effect. Two different devices have been fabricated and tested. The performance of an integrated lens and scanner device is demonstrated with electric field tunable focusing power and a scanning range of 14.6°. A 2-stage cascaded horn-shaped scanner is demonstrated with a scanning range of 25.4° at 5 kHz. Ferroelectric materials offer a unique platform for integrating several optical functions, like focusing, scanning, and frequency conversion, all in the same device.
