Abstract

We propose and demonstrate a novel polarization- and wavelength-independent digital electrooptic switch in <TEX>$Ti:LiNbO_3$</TEX> with switching voltage of <TEX>${\pm}$</TEX>32V at <TEX>$1.55{\mu}m$</TEX> wavelength. This <TEX>$2{\times}2$</TEX> integrated optic switch is characterized by a step-like response to the applied voltage. Switching is achieved through adiabatic mode evolution in an asymmetric waveguide junction. An average insertion loss of ∼4.5dB and polarization independent switching with average crosstalk of -12dB are achieved.
