title: Optical waveguiding in a single-crystal layer of germanium silicon grown on silicon.
abstract: Low-loss waveguiding at lambda = 1.3 microm has been observed in a partially strained, 10-microm-thick, single-crystal layer of Ge(0.1)Si(0.9) grown by chemical-vapor deposition upon an intrinsic (100) silicon substrate. The TM-mode propagation loss in the multimode planar guide was 1.9 dB/cm.
