Fast switching arrays of bistable elements, which utilize the innate parallelism of optics, will be required to operate efficiently with low incident powers, high switching speed, gain, good tolerance to noise, and minimal crosstalk between channels. An investigation of these competing criteria has been undertaken with an indium antimonide etalon using low power CW CO lasers, lead-salt diode lasers, and other sources of switching signals. Results are presented that characterize both the dynamic switching and noise dependence of single bistable channels and the transfer of switching in adjacent channels. These results can be used to assess the data rates, noise limitations, switching dynamics, and pixel densities that may be obtainable with the InSb system and could be appropriately scaled to other semiconductor etalons.
