A novel plane optical switch array device based on optofluidics is proposed,whose basic structure includes a core waveguide layer between a gas layer and a liquid layer.The liquid height of the optical switch unit is controlled by the pressure and the electrowetting effect to achieve full transmission and total reflection of light on and off.In addition, the optical switch parameters such as operating voltage, insertion loss and response time are discussed.The results show that this structure has lots of ad...
