Abstract :
Summary form only given. The switching time is much shorter that the switching time of the photorefractive process and thus this scheme can be used in such applications as the four-wave mixing and real-time optical holography. In conclusion, we have shown that intersubband absorption by the photoexcited carriers solves the problem of the delivery of the bias power to the optical switching elements without wires and lithography
