Abstract :
Summary form only given. We have demonstrated for the first time in a single 1×2 space switch based on absorption and refractive index change induced by the quantum confined Stark effect (QCSE) in multiquantum wells. It works with a single voltage and displays cross talk <-45 dB, a value which was only achievable with fiber switches.
