Abstract
A polarization independent variable optical attenuator (VOA) based on a dielectrically stretched liquid crystal (LC) droplet is demonstrated. In the voltage-off state, the proposed VOA has the smallest attenuation. As voltage increases, the LC droplet is stretched by a dielectrophoretic force, which gradually deflects the beam leading to an increased attenuation. Such a VOA can cover the entire C-Band. At lambda = 1550 nm, the following results are obtained: dynamic range similar to 32 dB, insertion loss similar to 0.7 dB, polarization dependent loss similar to 0.3 dB, and response time similar to 20 ms.
