Design and Simulation of Planar 4×4 Electrooptic Switches Based Ferroelectric Inverted Domains
An integrated 4×4 planar electrooptic switch is designed based on the electrooptic effect in ferroelectric inverted domains. It integrated four minute halfparabola shaped and four parabola shaped deflectors with the same configurations in a ferroelectric wafer. To optimize the design of the parabola shaped deflectors, an appropriate electrooptic switch is provided. Its properties of switch and exchange are analyzed using the beam propagation method (BPM). Simulation results show that the 4×4 planar electrooptic switch is feasible and the beam deflection errors can be compensated in practice by adjusting applied electricfield. The size of the optical switch is 48 mm×2.2 mm×0.5 mm and its maximum applied electricfield is about 13.73 V/μm. It has potential applications in highspeed optical exchange systems.
