Critical interpixel separation in nonlinear interference filters.
We work out the minimum interpixel separation for independent operation of as many as nine bistable devices forming a two-dimensional array on the same interference filter. This distance diverges as the holding power approaches the switch-up point of the single element and rapidly increases with the number of pixels. In a uniform area of 4 cm(2) approximately 50 pixels would operate independently with holding powers 15% off the single-element threshold.
