“…Leaky mode displays ultimately require numerous analog input waveforms in the RF regime, which, in the early days of this technology, are proving more cumbersome than well-established compact digital data interfaces and chipsets [16]. Coupling efficiency is also relatively low, both because it is difficult to achieve diffraction efficiency above 10% [23] (though high efficiencies have been reported [24,25]), and because it is desirable to have uniform efficiency across the interaction length, which keeps efficiency low by design. Many of these limitations are the subjects of ongoing research.…”

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.

“…2 In order to choose the transitions appropriate for frequency division of color, it is necessary to gather a large amount of carefully collected and correlated frequency input and angular output data for each color of interest. Figure 2 shows that a simple frequency response graph is insufficient to determine whether the design meets the requirements of frequency multiplexing of color.…”

This paper presents an optical apparatus for characterizing frequency multiplexing of color in leaky mode, anisotropic waveguide modulators. This type of characterization is particularly useful for informing the design of full color holographic video displays. The primary function of the apparatus is to map the frequency response and angular overlap of red, green, and blue outputs. The apparatus also allows measurements of other parameters such as scan center frequency, optical and RF bandwidth, and scan linearity.
