In this research we seek to develop acousto-optic, guided-wave modulators in proton-exchanged lithium niobate for use in holographic and other high-bandwidth displays.  Guided-wave techniques make possible the fabrication of modulators that are higher in bandwidth and lower in cost than analogous bulk-wave acousto-optic devices.  In particular, we are investigating multichannel variants of these devices with an emphasis on maximizing the number of modulating channels to achieve large total bandwidths.  Efficient, low-cost, monolithic modulators capable of modulating billions of pixels/sec should be possible.
