Abstract
We report the first demonstration of a guided‐wave polarization‐independent electro‐optic switch. Using a specially designed weighted Ti‐diffused directional coupler with stepped electrodes, we have achieved crosstalk levels below −23 dB for both switch states for arbitrary incident optical polarization.Keywords
