摘要： A semiconductor optical device includes at least a lower cladding layer formed on a semiconductor substrate, a core layer formed on the lower cladding layer, and an upper cladding layer formed on the core layer. The core layer includes a first core layer of a material susceptible to oxidation and a second core layer of a material unsusceptible to oxidation, the first core layer and the second core layer being connected in sequence in an optical propagation direction. The second core layer is formed at a facet where a light is input or output.

摘要： An optical integrated device comprises a substrate and a waveguide formed on a surface of the substrate. The waveguide includes a lower clad layer, a core layer formed on the lower clad layer and having a refractive index greater than that of the lower clad layer, and an upper clad layer formed on the core layer and having a refractive index smaller than that of the core layer. The waveguide further includes a straight waveguide part and a bending waveguide part curved in a plane parallel to the surface of the substrate. The lower clad layer in the bending waveguide part projects from the substrate by a projection height greater than that of the lower clad layer in the straight waveguide part.

摘要： An active area includes a photonic-crystal optical waveguide formed by periodically arranging a plurality of holes in a primary plane direction of an active-area core layer in an active-area growth portion. A passive area includes a passive optical waveguide formed in a passive-area growth portion. An effective refractive index of a growth structure of the active-area growth portion is larger than an effective refractive index of a growth structure of the passive-area growth portion, and an active layer has a gain at a zero group-velocity point positioned on a high-frequency side of a dispersion curve of the photonic-crystal optical waveguide.

摘要： A two-dimensional photonic crystal formed by arranging in a lattice pattern a medium having a refractive index different from that of a medium layer formed near an active layer. The two-dimensional photonic crystal includes a distributed-feedback control photonic crystal in which a light propagating through the active layer as a core is subjected to a two-dimensional distributed feedback within a plane of the active layer, and the light is not radiated in a direction normal to the plane of the active layer, and a surface-emission control photonic crystal in which the light is radiated in the direction normal to the plane of the active layer, which are superimposed with each other.
