摘要： A polarization independent optical device is provided wherein the device has two optical paths that include one or more birefringent crystals, a electrically controllable rotator, and a fixed waveplate. The device may operate as a switch, attenuator, coupler, or polarization mode dispersion compensator. The device may also include several folded path embodiments, a multifunctional embodiment, and a temperature insensitive embodiment.
