An optical switching device includes an array of liquid crystal macropixels, wherein each macropixel includes at least two liquid crystal subpixels. The subpixels may be controlled together to act as a single polarizing pixel, or independently to act as multiple polarizing pixels. When the switching device processes a WDM having a wide channel spacing, the subpixels are controlled together, and when the switching device processes a WDM having a narrow channel spacing, each subpixel is controlled independently.
