Weighted-coupling Y-branch optical switch in InGaAs/InGaAlAs quantum well electron transfer waveguides

Abstract

We demonstrate the first weighted-coupling Y-branch switch in semiconductors. The active waveguide core contains an InGaAs/InGaAlAs chopped quantum well electron transfer structure which provides large voltage-controlled refractive index changes near 1.55 /spl mu/m with high speed capability. We obtain polarization-independent switching over a wide… (More)
