“…We chose the last of these as our first optimization criterion. 10 Specifically, we sought to create a device that had bands of operation for red, green, and blue light that were adjacent in the frequency domain and overlapping in angular output. We wanted the individual color frequency bands to be as large as possible without causing the bands to overlap.…”

Abstract. We give a summary of the progress we have made in the fabrication of guided wave devices for use in holographic video displays. This progress includes identifying anisotropic leaky-mode modulators as a platform for holographic display, the development of a characterization apparatus to extract key parameters from leaky-mode devices, and the identification of optimized waveguide parameters for frequency-controlled color display.

“…If the wave guide is too shallow, the device may not work for red illumination. If the waveguide is annealed too long, the shape of the waveguide's depth profile will be distorted, and the red, green and blue transitions may not sit adjacent in the frequency domain 14 . In this work the authors present the tools and techniques to perform this characterization.…”

Holovideo displays are based on light-bending spatial light modulators. One such spatial light modulator is the anisotropic leaky mode modulator. This modulator is particularly well suited for holographic video experimentation as it is relatively simple and inexpensive to fabricate. Some additional advantages of leaky mode devices include: large aggregate bandwidth, polarization separation of signal light from noise, large angular deflection and frequency control of color. In order to realize these advantages, it is necessary to be able to adequately characterize these devices as their operation is strongly dependent on waveguide and transducer parameters. To characterize the modulators, the authors use a commercial prism coupler as well as a custom characterization apparatus to identify guided modes, calculate waveguide thickness and finally to map the device's frequency input and angular output of leaky mode modulators. This work gives a detailed description of the measurement and characterization of leaky mode modulators suitable for full-color holographic video.
