A variety of superlattices is predicted to exhibit high-speed carrier-activated light modulation. The proposal is based on the large, tunable, and very narrow absorption peak for transitions between the two lowest conduction subbands. The theory, which is demonstrated to be predictive, also suggests correspondingly large variations of the refractive index.
