Paper Abstract

In this paper, a new type of waveguide switch-field induced dynamic optical waveguide switch is presented. The switching mechanism is based on electric-field induced dynamic waveguiding effect in nanodisordered potassium tantalate niobate (KTN) crystals. By applying an electric field at different locations, different waveguide paths are created, which result in different output locations. The major advantages of this unique optical switch are broad bandwidth, covering the entire 1300 nm – 1600 nm fiber optic communication window, and ultrafast switching speed (on the order of nanosecond), which can be very useful for next generation optical networks such as the one used in data center networks.
