ABSTRACT:
An optical switch in which states are defined by dynamic charge storage, rather than contention resolution, and which switches using pulsed radiation having a wavelength somewhat longer than the exciton wavelength in a SEED diode. The switch does not exhibit or need bistability but switches at a relatively low energy as compared to S-SEEDS switched at the exciton wavelength.
