Notes:
Utilizing three electrodes and three independent voltages in Ti:LiNbO3 directional coupler optical switches, we have achieved significant improvements in switching extinction over the standard uniform Δβ configuration. The reductions in optical crosstalk vary from 3 to 24 dB for both switching states of several fabricated devices. We have observed a bar state extinction of −47.8 dB, which is the largest extinction ratio reported to date. We find that switching measurements are limited by the largest contrast ratio which can be obtained in the optical waveguides.
