    摘要： An integrated optical head includes a substrate and an optical waveguide formed on a surface of one side of a substrate. Light is directed to the optical waveguide and a grating structure is provided for deflecting light propagating in the optical waveguide toward the substrate. A distributed refractive index lens is formed in the substrate for condensing the light passing through the substrate after the deflection toward an article.

    摘要： This specification discloses an integrated optical circuit element comprising a substrate, a wave guide layer formed on the substrate and having a refractive index higher than that of the substrate, and a photocoupler which is a diffraction grating pattern formed in the wave guide layer and having the same refractive index as that of the substrate. The specification also discloses a method of making an integrated optical circuit element which comprises the steps of forming a mask of diffraction grating pattern on a substrate, forming a layer having a refractive index higher than that of the substrate in a portion of the substrate which is not covered by the mask, and removing the mask.

    摘要： A polarization-mode selective semiconductor laser includes a semiconductor laser structure including an active layer for generating gain spectra for the first and second different polarization modes and a diffraction grating formed with a uniform pitch over the laser structure. The laser structure includes a first DFB reflector portion with a first channel stripe and a second DFB reflector portion with a second channel stripe connected to the first stripe channel. The first DFB reflector portion and the second DFB reflector portion is serially arranged in a cavity direction of the laser. The first and second stripe channels are bent relative to each other such that a Bragg wavelength for the first polarization mode is coincident with a gain peak wavelength for the first polarization mode in the first DFB reflector portion, to make the first polarization mode dominant in the first DFB reflector portion, and that a Bragg wavelength for the second polarization mode is coincident with a gain peak wavelength for the second polarization mode in the second DFB reflector portion, to make the second polarization mode dominant in the second DFB reflector portion.
