Integrated electro-optic switch in liquid crystals

Opt Express. 2005 Jan 10;13(1):32-7. doi: 10.1364/opex.13.000032.

Abstract

We demonstrate a compact, low-power and broadband electro-optic switch in a simple waveguide geometry with undoped nematic liquid crystals. We experimentally achieve near infrared switching and signal routing with voltage modulations as low as 0.21V and a device length of 0.16mm.
