  • Abstract
    The phase change*interaction length product needed to switch a directional coupler is shown to be reduced by decreasing the coupling coefficient at the middle of the interaction region. With this improved structure, a voltage-interaction length product of 3.6 V cm was achieved with a LiNbO3 device at a 1.3 mu m wavelength.
