Optimized guided-to-leaky-mode device for graphics processing unit controlled frequency division of color

We present fabrication parameters for an annealed proton-exchanged lithium niobate guided-wave modulator, which has been optimized for frequency division color multiplexing. We present waveguide parameters that maximize individual color frequency bands while reducing the aggregate drive bandwidth to match the 200 MHz bandwidth of commodity graphics processing unit (GPU) outputs. By matching the device bandwidth to that of the GPU outputs, we have made possible highly parallel and scalable color waveguide displays.
