| 英文摘要 | PURPOSE:To increase an extinction ratio by disposing a clad layer having the refractive index smaller than the refractive index of optical waveguide layers to at least one of the optical waveguide layers and controlling the refractive index of the optical waveguide layers so as to attain the refractive index approximately equal to the refractive index of the clad layer by changing external modulating energy. CONSTITUTION:The refractive index of the InGaAsP waveguide layer is high and therefore the mode in which light propagates is a waveguide mode and the propagation less thereof is small. The refractive index of the InGaAsP waveguide layer attains n1=3.22 with respect to light having 5mum and can be approximated to the refractive index n2=3.18 of InP if said layer is constituted with the compsn.
