Abstract

We demonstrate the electro-activation of funnel waveguides through the quadratic electro-optic effect in paraelectric potassium-lithium-tantalate-niobate. This allows us to achieve electro-optic intensity modulation in a single optical beam, a 1×2 switch, and finally the electrically controlled morphing of a single waveguide into a 1×2 and a 1×4 divider.
