Abstract :
Two LiNbO/sub 3/-based Mach-Zehnder interferometric modulators with performance up to 40 GHz are cascaded in series to build a microwave-optoelectronic mixer. The dynamic range of the mixer is significantly enhanced by biasing the devices at quadrature. The mixer has potential for application in wideband fiber-optic communication systems.<>
