Surface-stabilized ferroelectric liquid-crystal electro-optic waveguide switch

Surface-stabilized ferroelectric liquid-crystal electro-optic waveguide switch

We demonstrate control of the optical coupling between a pair of planar waveguides by application of voltage to surface-stabilized ferroelectric liquid-crystal films between them. A prototype switch exhibited a response time of 200 μs and a 40:1 switching ratio.
