“…Qaderi et al also showed that polarization rotation and the lack of superfluous zero and higher orders made it possible to tile or stack devices in ways that would not be feasible with spatial light modulators [13]. Edge-stacked displays involving scores of devices would later be built to take advantage of this feature to create larger display areas [9,14].…”

“…To our knowledge, the system provided the first demonstration of a solid-state leaky mode holographic 3-D display. In response to input waveforms, the system projects simple real imagery (where the exit rays converge) or virtual imagery (from the apparent location of diverging rays) [9,14,61]. Unlike traditional spatially multiplexed autostereoscopic displays, such as lenticular displays, edge-exit leaky mode modulators produce numerous independently controllable "views" per output channel.…”

It will soon be a decade since leaky mode waveguide devices were presented as a solution for holographic video displays. This paper seeks to provide a brief, topical review of advances made during that time. Specifically, we review the new methods and architectures that have been developed over this period. This work draws primarily from papers seeking to present dynamic holographic patterns using mode coupling from indiffused waveguides on lithium niobate. The primary participants during this time period have been groups from the Massachusetts Institute of Technology, Brigham Young University, and Draper. We also describe the challenges that remain. The body of work reviewed speaks to the need for further development, but it also reaffirms that leaky mode waveguides continue to hold a unique place within spatial light modulation for holographic video displays.
