Abstract

In general, electrooptic switches are sensitive to the state of polarization. While this is not always an obstacle to their use in systems, there are many applications where the polarization of the light is not known or not constant. I present a lithium niobate optical 2x2 switch that is polarization independent at a wavelength of 1.3 μm. The switch operates at a relatively low 20 V, requires but a single control voltage, and exhibits up to 20 dB of crosstalk suppression. The theory of operation and experimental results are presented.
