Paper Abstract

Large change in the field induced refractive index is achievable by the use of the MQW structures. The property of which can be advantageously utilized to realize high speed external modulators and switches. The GalnAsP/InP MQW structures was prepared by LPE method and the electric field induced absorption was measured. Reflection of light due to refractive index change as well as absorption coefficient change was observed for the first time. Intersectional optical switch based on this change was also fabricated.
