We seek to fabricate massively parallel waveguide lithium niobate spatial light modulators as an enabling technology for the next generation of large holographic video displays. Holo-video displays based on acousto-optic (AO) modulators currently use 20 channels or fewer per AO device.  We are fabricating devices with 480 channels on a single substrate with each channel modulating light at 50 MHz bandwidth for a total of 48 Gpixels/sec of modulation, which is sufficient for VGA resolution, horizontal-parallax-only displays of one meter or more in width.
